Scattering problems for thin wire grid structures located over a simple lossy half space

In this work we investigate electromagnetic scattering from thin wire structures located over a lossy dielectric half-space by applying Green´s function formulation and Method of Moments in the resonance region and under “high contrast approximation”. The current distributions obtained under plane wave illumination on the arms of a cross shaped thin wire structure are compared to the same results obtained by the commercial software SNEC™.
