On aspects of the physical realizability of perfectly matched absorbers for electromagnetic waves

Authors


Abstract

[1] A discussion on the physical realizability of electromagnetic wave absorbers with perfectly matched impedances over arbitrary (i.e., doubly) curved, smooth surfaces is presented. The focus is on the analysis of the spectral characteristics (and their impact on the absorptive properties) of hypothetical material blueprints derived from the zero-reflection condition over such geometries.
