Not so much an issue

[EoghanMcGintyDCU]

Hi,

I wasn't sure how else to contact you. I've found your excellent repo and am embarking on a similar project for my masters in engineering. I had a couple questions regarding material definitions that I hoped you could answer. My biggest problem seems to be invoking plasmonic behavior in the 'gold' material. Here are two images
one of a dielectric material index=2

and the second is gold

much like you have defined, taken from the meep.materials library and 'scaled'. Same test, same time step. It looks like the EM waves pass right through the gold but we get these waves propagating along the dielectric circumference/interface.
My email is eoghan.mcginty3@mail.dcu.ie if it's easier to discuss there.

Thanks & kind regards,
Eoghan
