ALLOW SYMMETRY ON ALL BOUNDARIES: Allows symmetric boundary conditions with periodic structures (this option is not available in the boundary condition tab of mode sources and mode expansion monitors). Boundary condition options XMIN, XMAX, YMIN, YMAX, ZMIN, ZMAX BOUNDARIES: These fields describe ...
3、The most important detail to remember is that when using Periodic BC's, everything in the system must be periodic: both the the physical structure AND the EM fields. 我改了偏振以后 是不是periodic的呢?我不是很明白,我再看一看symmetric boundary condition是什么意思。 optics.ansys.com/hc/...

The method replaces the conventional single-angle incident wave with a constant transverse wave-number (CTW) wave, so the fields have no delay in the transverse plane, as a result, the periodic boundary condition (PBC) can be implemented easily for both normal and oblique incident waves. ...
the perfectly matched layer and the periodic boundary condition are applied to the graphene structure with two dimensional nano-materials. Numerical examples are carried out for further investigation. During the simulation, the influences of the parameters such as the grating slit and its thickness on...
