I have observed excellent acceleration. Dual-core systems have been
near-linear, and running on 8 machines with a GigE interconnect I got
about 6x acceleration.

MEEP does not simulate motion. In MEEP, all objects are fixed, and only
the electromagnetic field can change with time. Therefore, there is no
such thing as mass. Yo

The index of refraction of a material is only well-defined at a single
frequency. Meep works at all frequencies; therefore, the index of refraction
must be imp

You are absolutely right.
The key, for posterity's sake, is to first generate a polarizability with the
desired omega, gamma, and delta-epsilon, and an arbitrary sigma. Once t

Dear Meepers,
I am trying to define a polarizability with spatially varying sigma. My code
reads, in part:
(make polarizability
(omega omega_in)
(gamma omega_in)
(delta-epsilon (/ 1 omega_in))
