Dear all,
first of all: Thanks for you kind support!
I am trying to simulate a simple Bragg reflector made up of double layers
of Si3N4/SiO2using a Guassian source centered around 1550 nm (1/0.64).
(Meep/Python)
When simply using fixed epsilon values (e.g.: material = mp.Medium(epsilon
= 1.989*1.989)) everything works fine.
When instead - which is what I would prefer to do - referring to Meep's
material list for either SiO2 or Si3N4 (e.g. material = Si3N4_NIR) or
both, the simulation keeps aborting after some time steps with an error
message referring to the code line containing the "sim.run(...)"-command,
and giving the error message: "RuntimeError: meep: simulation fields are
NaN or Inf".
I have been scratching my head for some time now, so I was wondering if
you might give me a hint as to what might be going wrong here?
Thanks in advance!
Best
Sebastian
P.S. I could imagine that this topic has been raised in the past already,
unfortunately I didn't succeed in accessing the meep-discuss archive.
