Abstract
The modeling capability of the finite element-boundary integral (FE-BI) technique is expanded for the analysis and design of cavity-backed antennas and arrays consisting of complex, inhomogeneous, and anisotropic materials. The adaptive integral method (AIM) is implemented to accelerate the evaluation of the time-consuming boundary integrals. The modeling of anisotropic materials, impedance boundary conditions, and resistive boundary conditions is also addressed. Validation examples and comparison data are presented to demonstrate the acceleration and memory reduction achieved as a result of this enhancement.
