In this study, the authors present a thin wideband electromagnetic planar absorber for X- and Ku-band, which also has a polarisation-sensitive transparent window at frequencies lower than L-band. The design is based on a two-layer capacitive circuit absorber with the back-metal layer replaced with a polarisation-sensitive frequency-selective surface. The structure is studied for normal incident waves...
In this paper we present a comparison of two methods for radar cross section reduction (RCSR) of a wing-front profile. The aim is to reduce RCS over the frequency range 1-16 GHz in a forward sector of the traveling direction. We achieved a 5 dB reduction of the two dimensional mono-static radar cross section (RCS) for 68% (or more) of the frequency band for the polarization with the electric field...
A full-wave analysis for determining the resonant frequency and quality factor of a circular patch microstrip antenna printed on a uniaxial anisotropic substrate is presented. Green's functions of the structure are determined in Hankel transform domain (HTD) using Hertz potential vectors. Galerkin's method, together with parsval's relation in Hankel transform domain is then applied to compute the...
