FDTD Simulation Issue (metamaterial)


HMM focusing.fsp (393.8 KB)

I am simulating this structure but the simulation does not proceed.
i do not know why?



Dear @maisaad

Thanks to @gsun, we could come up with some ideas to help you solve the problem.

First of all, it looks like your Re(index yy) for HMM material is set to zero. Can you please explain why yo chose this value?

Also, it will be a good idea to use steep angle for your PML. The current setting might cause some problems when the incident angle is set to 70 when you sweep your source angle.

I hope this could solve the problem.
