【Abstract】 One-dimensional FDTD method is proposed for the transmission problem in multilayer medium. While the number of layers is 1, 3, 5 the reflection coefficients and transmissioncoefficients are obtained. It is shown that the one-dimensional FDTD method is very effective forsolving the transmission problem in complex medium.更多还原
