Abstract :
The authors present an iterative algorithm for reducing the error due to numerical dispersion while using the finite difference frequency domain (FDFD) scheme on Yee´s mesh in cylindrical coordinates. It is shown that the algorithm allows one to significantly enhance the accuracy of the results over a limited frequency band. Consequently, the algorithm provides a cost effective way of achieving high accuracy in the finite difference numerical analysis of such problems as computing resonant frequencies of empty and loaded resonators with cylindrical symmetry.
