摘要

The shielding problem consisting in the interaction between a dipole source and a Frequency-Selective Surface (FSS) is investigated. The Array Scanning Method (ASM) is adopted to take into account all the propagating and evanescent waves, which constitute the spectrum of the dipole and all the propagating and evanescent Floquet modes, which constitute the spectrum of the diffracted field by the FSS. The main differences with respect to the shielding of a conventional plane-wave source are pointed out, especially in terms of resonant frequencies, operating bandwidth and transmission levels.
