Resolution of 2-D time domain electric field integral equation with RWG functions using novel mesh technique based on hexagonal mesh

摘要

For efficient EM space modeling, it is very often needed an optimal type of meshing. Techniques and algorithms for meshing in triangles are much developed than another mesh type. In this paper, we present a resolution of 2-D time domain electric field integral equation with RWG functions (Rao, Wilton and Glisson's function) using novel mesh technique based on hexagonal mesh. (TD-IE) are applied to analyze transient radiation from square plate illuminated by an incident electromagnetic wave. A new basis function derived from RWG functions is used as space base and Laguerre functions as temporal basis function. Numerical results that validate and demonstrate the efficacy and accuracy of the proposed technique are presented and compared with another mesh technique.
