Meep Users, Since the implementation of metals seems to be a popular question, allow me to share a material list. The meep code has been generated with a script I obtained from Bala Juluri, which itself is adapted from the matlab/octave script LD.m by Bora Ung. To check these results, a 1 × 1 × 1 pixel region of dielectric was simulated and was exported with the command meep-fields-analytic-chi1, and then compared with LD.m
There's also fused silica, which matches quite well what you obtain from the Sellmeier equation. http://mpl.mpg.de/mpf/php/bfp/aw/meep-metals.pdf Enjoy! -- Aaron Webster (define myAg (make dielectric
