Efficiency of the IE-MoM approach in the analysis of dielectric bodies embedded in a cavity

摘要

This paper presents the analysis of dielectric bodies embedded in cavities made of perfect conducting metal using numerical approaches. For a case study of resource requirements a Dielectric Resonator Filter has been designed. Different numerical approaches were presented: FEM, FDTD, FIT, MoM and they were compared due to their computational effectiveness. Two of those method FIT and MoM showed a much higher efficiency than others. Their resource requirements were compared using simulations of a case study device. This paper shows that our Method of Moment with use of Green's function for stratified media has the best performance in solving dielectric bodies embedded in metal cavity. Therefore, there is a need to develop this method.
