[Meep-discuss] question on nonlinear calculation

2013-11-08 Thread nwuwl
Dear Steven and meep users Recently I tried to use meep to do calculation on nonlinear. But I’m confused on the calculation of refractive index change caused by nonlinear. This note (http://ab-initio.mit.edu/wiki/index.php/Units_and_nonlinearity_in_Meep) gives some details about my quest

[Meep-discuss] Fwd: Source in cylindrical coordinates

2013-11-08 Thread Oleksiy Onishchenko
Hello Steven and Meep users, I am trying to simulate an optical resonator, and I want to use cylindrical coordinates to take advantage of symmetry. In particular, the geometry is a mirror at, say z = 1 and another mirror at z = 5, and the resonator has radius 5, for example, with PML around. I have
