2012-09-01 Thread Steven G. Johnson
Any real-valued signal consists of both positive and negative frequency components (with complex-conjugate amplitudes) in a Fourier decomposition into complex exponentials. Harminv usually is set up to find just one sign of the frequency, but occasionally converges to a negative-frequency

My question is plain and simple. I have been wondering for quite some time now that why Meep's frequency domain solver does not seem to work. I have knocked on everyone's door that one can imagine, but have not found the answer yet. I have been trying to use meep's frequency domain solver to
