[MPB-discuss] Propagation constant with find-k function again

2008-11-08 Thread Yiling Qi
Dear Steven, Thanks for your suggestion before. As you mentioned, I really need to fix a frequency first, but the wavelength equals to 0.5um, and the lattice period is 11um( I am now repeating a result from PRL paper), which makes the frequency 22 in MPB, too big to find the root? On
