Rectangular vs. cylindrical finite-difference time-domain (FDTD) electromagnetic modeling is discussed, and characteristic tests and comparisons are presented depending on the analytical and numerical analysis of ring type circular resonators. A ring resonator is modeled with both rectangular- and cylindrical-FDTD packages which are also calibrated against analytical exact solution derived in terms of cylindrical Bessel functions. Applications of the periodic boundary condition in modeling circular (rectangular) structure via rectangular (circular) FDTD is also given.
