[Meep-discuss] (no subject)

Hi meep user Can I define two different polarized sources in the same structure? Is it possible to launch two different polarized (TE and TM) sources in 2D structure? is it possible to have both polarizations present at the same time in Meep? I want to simulate 2D structure with these sources

[Meep-discuss] Fwd: (no subject)

thats fine. You can even overlap the to launch a horizontally polarised source. Be careful though as you may only excite one set of orthogonally degenerate modes... J Sent from Samsung Mobile Original message From: Onder Karakilinc onderkarakil...@gmail.com Date: To: meep
