TL;DR: In this paper, a novel compact low-profile frequency selective surface (FSS) with controllable triband characteristics is presented, which consists of a stacked periodic array of square loops and complementary apertures, respectively centered within a wire grid and an aperture grid, which can create three transmission poles and two transmission zero.

TL;DR: In this paper, a novel optimization design method for circuit analog absorbers consisting of resistor-loaded square-loop arrays is proposed, which is applicable for multilayered absorbers with printed single or double SLAs on each layer.

TL;DR: In this paper, a combined-element frequency selective surface (FSS) is proposed for multi-band applications, which provides three transmission poles and two transmission zeros, transmitting the desired signals at 8.5, 11 and 16 GHz while reflecting the unnecessary signals at 9.6 and 13.1 GHz.

TL;DR: In this paper, an improved resonance cavity perturbation technique is employed to measure the complex permittivity of biological materials, including porcine fat, marrow, and liver, etc.

TL;DR: In this article, a miniaturized dual-band loaded frequency selective surface (FSS) with narrow band spacing is presented, in which each periodic cell consists of metallic patches connected with lumped inductors and capacitively loaded square loop aperture resonator printed on either side of a dielectric substrate.
