FDTD modeling of a super-thin finite conducting current sheet

An improved subcell FDTD model is developed and reported in this paper for efficiently simulating a super-thin current sheet. By fully incorporating in calculation the surface currents previously-ignored, the algorithm proposed herein thus represents a more general and precise approach for thin-sheet modeling than the traditional subcell scheme that has been favored for many years. The model development and validation are detailed in the paper.
