Re: [Meep-discuss] PML reflection problem

Dear MEEP users, first I am sorry for stating that no material should be put in PML. On the contrary, it can even help with the problem we discussed few weeks ago: I am convinced the problem is really in PML being able to amplificate the evanescent waves in the near field of the oscillator. After

Hi, Ali, as I suggested, try to make a BIG spacing between your structure and the PML. I recommend to give it as big spacing from PML, as the transverse dimensions are. I would be glad if somebody gives us some better suggestions on what to try next. It is also possible that it is the silver it

Hi Filip, Do you think the problem is related to the theory of PML or just a mistake in implementation in MEEP? I tried in the meanwhile different thickness of the silver layer and in all cases there was something like a resonance that I really do not know where it comes from and I do not know ho

Dear MEEP users, The structure I want to simulate using the meep c++ is so simple: a multilayer solar cell with a silver layer at the backside. So the structure looks like this: PML --- Air --- Silicon silver PML As far as I realized, one should try n
