I am trying to simulate a LiTaO3 structure using the material parameters from http://apl.aip.org/resource/1/applab/v85/i4/p543_s1 . There, omega_T/2pi = 26.7 THz, omega_L/2pi = 46.9THz and eps_inf = 13.4.
Is it enough to divide the frequencies by c/a in order to get the correct meep frequency units or further normalization is needed? Thank you very much! Harry Mavidis
