Design and Measurement of Frequency Selective Surfaces

Abstract

A new method for dimensioning a multiple layer Frequency Selective Surface (F.S.S.) based on an appropriate electromagnetic model will be examined. Feasibility and performance I imitations of F.S.S. having a single grid of Jerusalem crosses packed with several dielectric slabs will be analyzed. The technique of waveguide simulators is proposed as an attractive alternative to the radiation measurement technique. Experimental and theoretical results, in the frequency range of 8÷18Qk, are discussed in order to point out: the val idity of the measurement technique and the accuracy of the electromagnetic model.
