Abstract: A closed-form expression is derived for the numerical dispersion relation of the 2-D locally one-dimensional finite-difference time-domain (LOD-FDTD) method in lossy media. In contrast to the lossless formulation, we found that transverse-electric (TE$_{z}$) and transverse-magnetic… read more here.

DOI: 10.1109/lpt.2017.2693293
Abstract: An efficient implicit finite-difference time-domain (FDTD) algorithm in cylindrical coordinates is developed on the basis of a fundamental locally 1-D scheme. The Sherman–Morrison formula is introduced to treat a cyclic matrix and the image theory… read more here.
