On the Design of Wide-band and Thin Absorbers Using the Multiple Resonances Concept

摘要：

This paper describes how one can design a wide-band and thin absorber using the multiple resonances concept.Employing a simplified and yet intuitive equivalent circuit model,we can demonstrate that a thin absorber with a wide bandwidth can be designed by introducing multiple resonant circuits in the substrate backed by a planar conductor whose radar cross-ection(RCS) is to be reduced.A few design examples,including double square-loop printed on a substrate,circuit analog (CA) absorber using multiple resistor-loaded dipoles,and shunt-series connection of transmission line structures are presented to demonstrate the wide-band performance of a thin absorber utilizing a structure with multiple resonances. Both simulated and measured results are provided and compared.
