Fundamental Limitation on the Performance of Chiral Radar Absorbing Materials

Abstract

We show that a fundamental limitation exists on the integral of the dB-reflection coefficient over wavelength for a passive metal-backed absorber, whose value is determined by the low- frequency behaviour only. This limit is the same for dielectric absorbers, and for chiral and omega absorbers.
