Efficient calculation of interior scattering from large three-dimensional PEC cavities

FG Hu, CF Wang, YB Gan - IEEE transactions on antennas and …, 2007 - ieeexplore.ieee.org
Higher order finite element-boundary integral (FE-BI) method is a powerful tool to model the
electromagnetic (EM) scattering from three-dimensional large, deep, and arbitrarily-shaped
cavities. To further understand the higher order FE-BI method and its applications to the
modeling of interior scattering from very large practical perfect electric conductor (PEC)
cavity structures, two aspects will be discussed in this paper. The first is on the development
of a new integration method to accurately handle singular integrals in calculating BI matrix …
