Ivar Kjelberg please help! About the shape of PML in comsol 4.4

Dear Ivar Kjelberg, I have a question in my simulation. I use the RF module, I was calculating the effective index of the photonic crystal fiber. The shape of the cross section is a hexagonal, the...

I have the same problem. Does anybody know how to solve it?

I solved it myself, do not set an arbitrary shape of PML, just use circular or rectangular. By careful mesh, the results will be good!

3D spherical maybe easier, you can refer to the example model of comsol(for example, dipole antenna ), do not forget to use swept mesh! I hope this help.

Re: Ivar Kjelberg please help! About the shape of PML in comsol 4.4

Hello, I am new to Comsol. I tried to make a simple 2D axisymmetric model with a core circular region 5um in radius of refractive index 1.7 and 0.5 um thick outer circular region of refractive index...

When the geometry is set to be cylindrical, the problem should have been solved. Moreover, your PML is too thick, one or two lmd is ok!
