Abstract: In order to study the reflection of electromagnet ic wave in Lorentz media, A novel piecewise linear recursive convolution(PLRC) method based on the auxiliary differential equation (ADE) of finite-difference time-domain(FDTD) technique is used to obtain the formulation of 2-D TM wave propagation in lossy Lorentz media. In 1-D case, the reflected coefficients calculated by the PLRC ADE-FDTD method and exact theoretical result are excellent agreement. This expresses that the 2-D formulas of electromagnetic wave propagation in lossy Lorentz media are right. Furthermore, Plane wave reflected by Lorentz media layer is calculated and simulated. Results display that reflected effect is evident.
