Hi,
Does anyone know if Meep does any sort of correction for numerical dispersion
(see J. B. Schneider, and C. L. Wagner (1999) "FDTD dispersion revisited:
Faster-than-light propagation
<http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=755044>”, IEEE Microwave
and Guided Wave Letters 9 (2): 54–56.)?
If a correction is not automatically made in Meep, would it make sense to
adjust dielectric constants in a calculation to compensate? Is anyone aware of
subtle inaccuracies that might result from doing this?
Glenn
