“…The oblique incidence does not bring essential difference into mathematical derivations, but due to the "splitting" of resonances, see [15], it gives more complicated pictures of diffraction characteristics and makes the physical analysis vaguer. The diffraction field E ∂ , H ∂ has to satisfy:…”

Abstract-Scattering of electromagnetic waves by periodic stripe grating backed with a layer of metamaterial is considered. The distinguished feature of the structure is the association of periodicity of two scales: Micro scale that is the scale characteristic to metamaterial of the layer, and the scale of periodic metal stripe grating that is of the scale of wavelength of incident electromagnetic field. Such association gives rise to new type of resonant phenomena such as "crowding" of resonant transmission/reflection peaks in the vicinity of characteristic frequencies of the structure. The study of the problem is performed on the base of rigorous and accurate solution to the diffraction and spectral problems, which guarantees the robustness of numerical algorithm; and allows asymptotical analytical analysis of the problem and prediction of various resonant phenomena.

Abstract-We present a generally symmetrical circuit model to describe all kinds of metamaterials with effective permittivity and permeability. The model is composed of periodic structures whose unit cell is a general T-type circuit. Using the effective medium theory, we derive analytical formulations for the effective permittivity and effective permeability of the circuit model, which are quite different from the published formulas [1,2]. Rigorous study shows that such a generally symmetrical model can represent right-handed materials, left-handed materials, pure electric plasmas, pure magnetic plasmas, electric-type and magnetic-type crystal bandgap materials at different frequency regimes, with corresponding effective medium parameters. Circuit simulations of real periodic structures and theoretical results of effective medium models in this paper and in [1] and [2] are presented.The comparison of such results shows that the proposed medium model is much more accurate than the published medium model [1,2] in the whole frequency band.

A beam combiner, which can combine multiple Gaussian beams into a single one, has many important applications, such as high-power radar and weapon. In this paper, we propose a new scheme of the design of high-power beam combiner at millimeter wavelengths by using wire grids. The design tool is to combine a genetic algorithm (GA) for global optimization and an Ansoft HFSS for rigorous electromagnetic computation. The design method is described in detail and the optimized results are presented. Finally, a brief summary is given.
