In this paper, A new alternating direction decomposition(ADD) solution method is used for the split-step Fourier algorithm of the parabolic equation. The diffraction term factor is approximately ...

Defect modes of a photonic crystal modulated by propagating acoustic wave are investigated using supercell plane-wave expansion method. It is show that as a result of dielectric permittivity ...

With the advent of post-Moore era, the development of memory devices based on bulk materials gradually entered the bottleneck period. Two-dimensional (2D) materials have received much attention due to ...
