Hi dear.

there are two ways.

1)Home-->Macros-->material-->creat graphene material for optical appliocation

2)model graphene epsilon in matlab using formula eps=1+4*pi*i*sigma/(omega*t) where t is the thickness of graphene layer=~0.34 nm and sigma is the conductivity.

in the result you must get frequency eps' eps'' and export in text format using ''dlmwrite'' command. then you must import it in cst from material-->dispersion.

Hope to help you.

Hi dear

can you please share the step by step procedure of graphene modeling in CST to [email protected]
