Abstract
An implicit finite-difference time-domain method in cylindrical coordinates is developed using the locally one-dimensional (LOD) scheme. The Sherman-Morrison formula is utilized to solve a cyclic matrix resulting from the application of the implicit scheme to cylindrical coordinates, and the image theory is introduced to treat a perfect electric conductor. The convolutional perfectly matched layer is also incorporated into the cylindrical LOD-FDTD method. An efficiency improvement is briefly discussed for the analysis of a metal disc-shaped surface wave splitter.
