A new FDTD model in the study of hollow conducting elliptical waveguides and cylindrical cavity resonator

摘要

A new FDTD model is investigated to analyse electromagnetic wave propagation in a hollow conducting elliptical waveguide and a 3D cavity resonator using a Cartesian co-ordinate system. Modifications based on a nonorthogonal FDTD method are presented which are more efficient than general nonorthogonal FDTD schemes in terms of computer resources such as memory and CPU time
