Radiation from vertical sources placed inside a grounded dielectric slab covered with a thin microstructured metal screen with annular geometry is studied. The screen is represented by a locally homogenized surface impedance dyadic. We propose both analytical and numerical models for the calculation of the far-field pattern. The results are validated through rigorous full-wave approaches.

Abstract
Radiation from vertical sources placed inside a grounded dielectric slab covered with a thin microstructured metal screen with annular geometry is studied. The screen is represented by a locally homogenized surface impedance dyadic. We propose both analytical and numerical models for the calculation of the far-field pattern. The results are validated through rigorous full-wave approaches.File in questo prodotto:
