FVTD Analysis of Bended Waveguides

Abstract

This paper is concerned with a finite volume time domain (FVTD) analysis for the electromagnetic wave propagation in bended waveguides. FVTD method is based on the volume integrations of the Maxwell's equations with respect to regular hexahedron cell. The electromagnetic fields in the regular hexahedron cells are expressed in terms of the tangential electromagnetic fields on the surfaces of the cells, and the latter field components are given by the interpolation of the former fields of the adjacent two cells. The advantage of the FVTD method is that the impositions of the boundary condition are easy.
