The frequency-selective shielding behavior of periodic screens based on resonant elements is investigated, with particular reference to two-dimensional arrays of Jerusalem crosses and split-ring resonators. A parametric study of the shielding effectiveness under plane-wave far-field incidence is first performed based on a conventional periodic Method-of-Moment approach and verified through other full-wave commercial software simulations. Next, an Array-Scanning Method technique is used to study the shielding properties against finite dipole nearfield sources, pointing out the main differences with respect to the far-field excitation.

Abstract
The frequency-selective shielding behavior of periodic screens based on resonant elements is investigated, with particular reference to two-dimensional arrays of Jerusalem crosses and split-ring resonators. A parametric study of the shielding effectiveness under plane-wave far-field incidence is first performed based on a conventional periodic Method-of-Moment approach and verified through other full-wave commercial software simulations. Next, an Array-Scanning Method technique is used to study the shielding properties against finite dipole nearfield sources, pointing out the main differences with respect to the far-field excitation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
