Abstract	Electromagnetic absorbing materials have been extensively studied for use in reducing reflections for a wide variety of applications, ranging from stealth technology to anechoic chambers. One of the most popular techniques is based on a Salisbury screen design, which consists of a resistive sheet placed a quarter-wavelength above a PEC ground plane separated by a dielectric layer [1]. However, for many applications the Salisbury screen is prohibitively thick and a more compact structure is desired. Recently, metamaterial surfaces have been utilized in the design of thin absorber screens [2]. Additionally, they have been utilized in the design of ultra-thin single-bandgap electromagnetic absorbers [3], which were based on using a genetic algorithm to optimize a metallic pattern printed on a very thin dielectric substrate backed by a PEC ground plane. Electromagnetic interference due to multiple reflections also poses a problem for wireless local area networks, and therefore designs that minimize this effect are also of interest. To suppress multiple reflections, a novel absorptive/transmissive FSS was investigated in [4] using a two layer cross dipole FSS screen, while a double-sided permeable wave absorber based on a resistive film design was reported in [5].
