Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. The "best effort" Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed QoS services as well as high rate communications.

The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough resources available in some parts of the network the mobile user is moving into. The emerging Internet QoS architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.

This tutorial covers to the issues of QoS provisioning in heterogeneous networks and Internet access over future wireless networks. It discusses the characteristics of the Internet, mobility and QoS provisioning in wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking protocols and end to end traffic management issues.

Ground Penetrating Radar (GPR) is a safe, effective, non-destructive and non-invasive inspection technique, providing high resolution images of subsurface and structures through wide-band electromagnetic waves. GPR radargrams often have no resemblance to the scenario over which the profile was recorded. Various factors, including the innate design of the survey equipment and the complexity of electromagnetic propagation in the ground/structure, can disguise how structures get recorded on GPR reflection profiles. In this context, electromagnetic-modelling techniques are of paramount importance. They can be employed to aid the interpretation of experimental datasets, highlight capabilities and limitations of GPR, and to understand where and in what environments this inspection method can be effectively used. Electromagnetic simulations can support the choice of the most proper GPR equipment for a survey and are useful to design and optimise new GPR antennas. Synthetic radargrams can be specifically conceived to test new data-processing/imaging algorithms or assess the effectiveness of existing ones. Finally, a fast and accurate electromagnetic forward solver can be embedded in an inverse electromagnetic solver and be used for automatic interpretation of data.

This Tutorial is composed of four parts.

In the first part, an overview on the European research on GPR and its applications is provided. Four main research areas can be identified: (i) The design and realisation of novel GPR systems and antennas; (ii) The use of GPR for a plethora of different tasks in civil and environmental engineering, geology, archaeology, management of water resources, planetary exploration, forensics, security and more; (iii) The development of electromagnetic-modelling, imaging, inversion and data-processing techniques; (iv) The integration of GPR with complementary non-destructive testing (NDT) methods.

In the second part, a quick perspective on available electromagnetic-modelling techniques for GPR is given. In order to predict correctly the GPR response to a given scenarios, Maxwell’s equations have to be solved, subject to the physical and geometrical properties of the considered problem and to its initial conditions. As is well known, several approaches have been developed in computational electromagnetics, for the solution of Maxwell’s equations. These can be classified into two main categories: differential and integral equation solvers, which can be implemented in the time or frequency domain. Differential solvers include, inter alia, the Finite-Difference Time-Domain (FDTD) and Finite-Volume Time-Domain techniques, the Finite-Element and Transmission-Line Methods, and the Cylindrical- and Spherical-Wave Approaches. The Method of Moments is an established integral-equation approach. All of the different techniques present compromises between computational efficiency, stability, and the ability to model complex geometries. Commercial simulators implementing these techniques are very often used, but interesting freeware alternatives exist: during this part of the tutorial, information is also provided about reliable tools available on the web free of charge.

The third part of the tutorial is focused on introducing gprMax and E2GPR. gprMax is a freeware FDTD simulator implemented in The University of Edinburgh (United Kingdom). A new version based on Python has been recently released, which includes noteworthy advanced functionalities such as the possibility to include in the model objects with inhomogeneous dielectric properties and rough surfaces, as well as anisotropic or frequency-dispersive materials (following multi-pole Debye, Lorenz or Drude formulations); built-in libraries of antenna models are also available. E2GPR is a freeware tool developed in Roma Tre University (Italy) to assist in the creation of two-dimensional gprMax models through a Computer-Aided Design system, ease parallel/distributed computing with gprMax and plot the results. Both tools represent a contribution to COST Action TU1208 “Civil engineering applications of Ground Penetrating Radar.” Notwithstanding they are conceived to allow electromagnetic modelling of GPR scenarios, they can be employed to compute numerical solutions to any electromagnetic radiation and scattering problems.

During the fourth and last part of the Tutorial, the TU1208 database of GPR data is presented. This is a collection of experimental and synthetic radargrams obtained in the presence of manmade and natural structures, at the disposal of the scientific community. Aim of this initiative is to give researchers the opportunity of testing and validating, against reliable data, their electromagnetic forward- and inverse-scattering techniques, imaging methods and data-processing algorithms.

Modern antennas for mobile devices, especially mobile phones, must support multiple wireless services that are transmitted over different frequency bands (e.g. GSM, UMTS, LTE-A, Bluetooth, Wi-Fi, GPS). Although a particular antenna is based on some of the common canonical antenna designs, canonical designs do not often meet the multiband specs that are sought in modern antennas and antenna engineers must resort to creative noncanonical designs that will then achieve their goals. This tutorial will make an overview of the essential theory encompassing microstrip antenna design (as the most popular choice) and discuss innovative solutions in meeting the multiband characteristics of novel antenna designs. The tutorial comprises four parts as described next.

The first part will contain an essential microstrip antenna theory. We will review the microstrip antenna concept and structure of common types of microstrip antennas, including a brief discussion on common types of feed.

The second part will focus on the design aspects of one of the most popular choices - a rectangular microstrip antenna. The geometry and most popular feed types will be reviewed first, followed by the analytical models that provide satisfactory solutions. Lastly, the notion of the modes of operation and the corresponding resonant frequencies will be introduced.

The third part will cover antenna design aspects by means of computer-aided design. Electromagnetic modeling features using one of the commercial EM CAD tools will be presented and then implemented on a few designs of microstrip antennas. For the canonical design case, we will compare the analytical and numerical solution, while for the noncanonical cases, we will pay attention to the powerful features provided by the modern CAD tools (such as structure design tuning, parameter sweep- or optimization- option).

In the last part, we will show examples of various multiband antenna designs and interpret the approaches used in them to achieve the design goals. Use of slots in the patch geometry is one of the modern techniques to create multi-resonance behavior of the microstrip antenna and we will discuss the effects of the slot geometry on the antenna resonant frequencies. Moreover, use of shorting pins and diodes, as additional instruments in the modern antenna design, will be illustrated. Lastly, we will show the results of a recent investigation of interpolative computation of the slot dimensions of a rectangular microstrip antenna, that avoids a direct usage of a full-wave EM code, based on a predefined number of reference data samples that were acquired in advance on a reference antenna model.

The deterministic prediction of microwave and electronic circuits and devices is nowadays insufficient, since uncertainties always exist in reality. These uncertainties cause the system variables to deviate from their nominal values, thus making the deterministic results unsuitable for the development of high-performance electronic products due to the urging necessity to perform right-the-first-time designs. Stochastic analysis is extremely useful in the early design phase for the prediction of the system performance and for setting realistic margins whenever manufacturing tolerances or uncertainties on design parameters cannot be neglected. With the scope of developing efficient design tools, outperforming classical but time-consuming sampling-based techniques like Monte Carlo, new techniques have been proposed. The presentation will provide a summary of techniques belonging to the two broad classes (intrusive and non-intrusive) of Uncertainty Quantification and will discuss very recent advances developed with the aim of addressing the problem of the curse of dimensionality. The theoretical framework will be complemented by simple examples related to Electromagnetics, Microwaves and EMC to illustrate the feasibility and the interest of uncertainty approaches in real applications.

Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library. Julia’s Base library, largely written in Julia itself, also integrates mature, best-of-breed open source C and Fortran libraries for linear algebra, random number generation, signal processing, and string processing. In addition, the Julia developer community is contributing more than 1000 external packages through Julia’s built-in package manager at a rapid pace. IJulia, a collaboration between the Jupyter and Julia communities, provides a powerful browser-based graphical notebook interface to Julia. Julia programs are organized around multiple dispatch; by defining functions and overloading them for different combinations of argument types, which can also be user-defined." (from http://julialang.org) In this tutorial we will cover basics of Julia principles and usage and, time permitting, few advanced application examples.
