In this paper, a new wideband single-layer lossy frequency selective surfaces (FSS) absorber using Double Fractal Square Loops (DFSL) array is proposed. A unit cell of the periodic structure for the absorber is designed and simulated. A simple equivalent circuit model is proposed that predicts the plane wave transmission characteristics for normal incidence. The absorber consists of a copper layer...
This paper describes an enhanced thin and wideband circuit analog (CA) absorber consisting of square-loop arrays. The enhanced design replaces the metallic backplate of a circuit analog absorber with a conductor-backed resistor-loaded high impedance surface (HIS). First, a wideband single-layer CA absorber with metallic backplate is designed. The metallic backplate is then replaced by a conductor-backed...
A detailed study of a single-layer circuit analog absorber using double-square-loop array reveals that three resonances can be obtained within its operating frequency band. An equivalent circuit model is proposed to explain how these three resonances can be produced and its absorption bandwidth can be widened. Simple guidelines for the design of this double-square-loop absorber are then formulated...
