Applications of Runge-Kutta Multiresolution Time-Domain scheme in dielectric media interfaces

In the paper, we have discussed applications of the Runge-Kutta Multiresolution Time-Domain Scheme (RK-MRTD) in dielectric media interfaces for the first time. The RK-MRTD results have been compared with those of analysis results about the MRTD method in a media layer structure. It has been shown that the RK-MRTD scheme is more accuracy. And the application field of the RK-MRTD method is expanded. In addition, we find that the high-precision features of the RK-MRTD method could not be displayed when we use the main diagonal approximation to simplify the update equations for treating the dielectric media interfaces.
