Abstract :
An advanced FDTD algorithm has been applied successfully to the analysis of a cylindrical cavity coupled by two different irises to feeding WR 75 waveguides. Several sophisticated features such as modal absorbing boundary conditon, Prony´s method and a new technique to approximate curvilinear surfaces, have been implemented. The effectiveness of the method is proved by the good agreement with experimental results and by the reduced computational effort compared to previous similar analyses of cylindrical structures.
