Abstract

The recently developed spatial finite-difference and temporal differential (SFDTD) approach is extended to dielectric loaded cylindrical environments. Although the method is developed differently, its resultant formulation can be directly obtained from the corresponding finite-difference time-domain (FD-TD) method. Good agreements between the SFDTD and reference results are obtained for different configurations of dielectric loaded cylindrical structures. As a result, the SFDTD approach is shown to be generally effective and robust for resonant structures
