Abstract
Conference Title: 2013 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2013, July 7 Conference End Date: 2013, July 13 Conference Location: Orlando, FL, USA The paper presents an efficient and accurate technique for the analysis of large, finite and conformal Frequency Selective Surfaces (FSSs) which are not amenable to analysis by using conventional methods. The proposed technique is based on the Characteristic Basis Functions (CBFs) to describe the currents induced on the FSS elements. The reaction integrals needed to derive the reduced matrix elements are either computed in the spatial or spectral domains depending on their separation distance, so as to make the process numerically efficient.
