The electric field integral equations (EFIE) solved by method of moments (MOM) is widely used in scattering, antenna, and microwave circuit problems. However, it is well known that EFIE will break down when applied to electrically small structures or low frequency problems. A loop-star decomposition for the RWG discretization overcomes this problem and provides a valid solution from zero to microwave...
It has recently been observed that local-global solution modes provide a useful framework for the development of fast, direct solutions of integral equation formulations of frequency-domain electromagnetic radiation and scattering problems. In particular, overlapped, localizing LOGOS (OL-LOGOS) modes have been observed to provide a fast direct solution procedure with approximately O(N) memory and...
Integral equation-based numerical models provide an important tool for the analysis and design in a variety of application areas. Traditional implementations of IE-based models lead to dense matrices, and this significantly limits the range of problems that can be addressed using such approaches. To treat more complex problems, it is necessary to use more sophisticated methods which rely on compressed...
