I'm following up from my recent thread here: (
https://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg05449.html)
because after further testing I realize that my original suspicion was
wrong, and I want to get opinions from those who might otherwise ignore
this topic because of that
Hi, Glenn,
in my experience, the speed of light and generally the results in MEEP
are quite accurate (compared to theory, other methods or experiment)
until the wavelength becomes comparable to several voxels - in which
case however also the structure ceases to be described correctly. Thus
I
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):
Dear all,
I am writing a diploma thesis which mentions FDTD and I would like to refer
the Meep with its capabilities. May I ask you, how does the Meep solves
problematics of numerical dispersion. Do you use any specific method to
reduce it?
I'm looking forward to hearing from you,
Best wishes,
Currently there are no explicit methods used in Meep to account for
numerical dispersion effects that result in numerical waves to propagate
with direction-dependent phase velocities within the Yee grid. In
general, the effects of numerical dispersion are rather weak as
illustrated in an
