BOR-FDTD for axially symmetrical diffraction grating calculation

In paper Body of Revolution Finite Difference in Time Domain (BOR FDTD) method is used for calculation of the diffraction of modes of a hollow dielectric waveguide on axially symmetric grating with many periods. The effective absorbing boundary conditions for this method in form of Perfectly Matched Layer (PML) are presented. Reflection and transmission coefficients and field distributions for different modes are obtained.
