True for isotropic medium. But if there is an interface between different
media, the TE and TM mode transmission would be quite different due to the
boundary conditions. Normally for 2D PC structure, it's enough to separate the
problem into TE and TM mode, basically the electric field is inplane or
vertical to the dielectrics and they are still a scalar wave. But if you
consider the surface roughness of the holes, the radiation loss, you will have
to use vector electromagnetic theory. Mostly in |
