Hi all meep users
There are many questions about negative epsilon in meep-discuss If negative epsilon was used, simulation would be unstable and blow up to infinity. I want to use negative epsilon for real metal such as Al and Ag. So I tried to search this problem in meep-discuss, and I could find the response that material dispersion should be used. Therefore, I applied material dispersion, but flux was increased to infinity, too. I hope that a example which use the negative epsilon would be listed in meep homepage or meep-discuss. If I missed the example about negative epsilon in meep-discuss, please inform me. Sincerely Hwan-Hee Cho.
