Toward the Modeling of Thin Conductive Layer With Hybrid FDTD-PITD Method

A novel hybrid algorithm is proposed to model the embedded thin conductive layer (TCL). The finite-difference time-domain method is adopted for coarse grids outside TCL and the precise-integration time-domain method for one-dimensional fine grids inside TCL, synchronously updating the fields of different grids. Numerical results confirm the efficiency and accuracy of the new hybrid method.
