3d simulation in rf module

Please login with a confirmed email address before reporting spam

Hi,

I was trying some simulations in 3d, rf module.

In the first simulation (nw_3d.mph) I just have a block of 100nm*100nm*4um. The whole block is filled with air (n_Air=1). Lambda=600nm. I have a scattering boundary condition at the top with incident plane wave. The bottom surface is a PEC. There are periodic boundary conditions along x and y directions....... this simulation seems to be working okay.. I get the standing wave.


In the second simulation (nw_3d_2.mph), I have the same conditions. The only difference is I now include a cylinder inside the block... but still keep the refractive index =1 everywhere (I will change the refractive index of the cylinder later on).... but this time I am not getting the previous results. There seems to be some points in the solution with very high values of abs(Ey).

How do I fix this??

Thanks.

Ryyan.
