A technique is proposed to achieve significantly better detection, discrimination, and automatic identification (id) for stationary or slow-moving range-Doppler over-resolved targets on or in close proximity to the ground (or sea surface). This technique is based upon a generalized inner product (GIP) approach to data analysis. This robust detector/discriminator separates radar returns from interference including ground clutter via a coherent process for separating target returns from the myriad of received signals. Through the use of coherent target templates artificial intelligence techniques will be developed to automatically id targets without human intervention.

The problem of scattering of plane electromagnetic wave on the infinite microstrip lattice with nonlinear loads in the strip plane was solved when a metamaterial (MM) is used as lattice substrate. It is shown that an application of MM as a substrate (instead of a dielectric) provides alignment of levels of the higher harmonics in comparison with first harmonic in the reflected field. It is reached due to suppression of fundamental harmonic in the reflected field. Also it is shown a possibility to increase the efficiency of the infinite microstrip lattice with the nonlinear elements, with a using of MM as a substrate, by means of a constructive synthesis of the geometrical sizes of the lattice.

We discuss the application of the sparse processing techniques in the differential breast-cancer imaging. We derive the sparse model by assuming that the parameters of the inhomogeneous breast model are known from the previous measurements. In the linear model, we use the numerically computed three-dimensional Green's functions. We investigate the role of the regularization parameter and the number of sensors on the solution accuracy.

In this work, a virtual laboratory for modeling Wireless Power Transfer systems is presented. It is based on the Finite Element Method and is fully parametrized, so as to analyze various coil configurations. A 3D FE formulation is moreover considered in order to model coil misalignments. The numerical results are compared with analytical formula and experimental measurements.

This paper analyzes and compares two types of transmission line metamaterials: (i) coplanar waveguide (CPW) transmission lines loaded with pairs of magnetically coupled split ring resonators (SRRs), and (ii) microstrip lines loaded with pairs of electrically coupled complementary split ring resonators (CSRRs). Both structures are described by lumped element equivalent circuit models rather different. However, both structures exhibit very similar phenomenology, and there is a mapping between the elements of both models that gives identical results for the analytical expressions providing the resonance frequencies (transmission zeros) that these lines exhibit. It is shown that these artificial lines are useful as dual-notched filters and as differential sensors and comparators.

An alternative approach to the International Standard criteria used to assess the well-operating of a reverberation chamber (RC) is proposed. The considered indicators, inspired from studies on chaotic cavities, rely on the properties of the cavity resonant frequencies. The new proposed approach aims to reduce the measurement duration and improve the reliability of the RC minimal operating frequency estimation.

A linear (optimal) complexity direct solver not only can significantly accelerate the forward analysis of electromagnetic problems, but also open up a new solution space for fast inverse design (synthesis). In this work, we show how the layout synthesis of electromagnetic structures can be transformed to an equivalent inverse problem, and subsequently solved by a linear-complexity direct finite-element solver without the need for an optimizer.

The spherical-multipole analysis is used to describe the statistics of an electromagnetic field in a shielding enclosure whose geometry is known by its statistic moments only. All of the statistical information is contained in a few scalar spherical-multipole amplitudes. Numerical results prove the correctness and usefulness of the approach. Moreover, the statistical spherical-multipole expansion is a promising candidate for compactly expressing the shielding effectiveness of a spherical domain, and not just at a certain point inside the shielding enclosure.

BRAMS (Belgian RAdio Meteor Stations) is a network of radio receiving stations using forward scatter techniques to study the meteoroid population. The main goals are to compute meteoroid flux rates and mass indexes, determine individual meteor trajectories and orbital parameters of meteoroids, and to analyse meteor profiles in order to retrieve physical parameters of the meteoroids. For that purpose, a dedicated beacon is used together with 26 single-antenna receiving stations spread over Belgium, one dual antenna station and one interferometer. The instrumentation of this network is described in this paper.

Plasmonics - the interaction of light with free electrons in metals - is commonly understood within classical electrodynamics using local-response constitutive laws (such as Ohm's law). However, the tight localization of plasmons to small volumes is revealing intriguing new physics such as nonclassical electrodynamics with a nonlocal response of the plasmons. Nonlocal effects are being explored both theoretically and experimentally in different charge-conducting material systems with examples ranging from sub-10 nanometer noble metal particles to one-atom thin disks of doped graphene.
