Abstract

Periodic arrangements of metallic scatterers have in the past decades found numerous applications as Frequency Selective Surfaces [1]. More recently Artificial Magnetic Conductors (AMCs) [2] have been presented based on arrays printed on grounded dielectrics. AMC and FSS have been employed to reduce the profile of Salisbury screen absorbers in [3] and [4] respectively. Another variation where the resistive sheet was substituted by a resistive FSS and the ground plane by a metallic FSS was presented in [5]. AMC structures have also been proposed as thin absorbers. A double square loop AMC where lumped resistors were embedded in the metallic elements was proposed as thin absorber in [6]. In [7-9] AMC structures consisting of resistive elements were proposed, while [10] suggested the use of metallic AMCs on lossy substrates. Tunable designs are presented in [11] based on liquid crystal (LC) technology.
