FDTD Simulation of Thin Resistive Sheets

An effective approach is presented for simulation of thin resistive sheets in FDTD.  The approach is based on surface impedance and piecewise linear recursive convolution technique.  This approach can be combined with a conformal scheme so that it can be applied to deal with an arbitrarily shaped thin sheet.  The simulation results for a couple of examples have shown that the approach is robust, stable and quite accurate.
