I am trying to simulate an optical antenna in HFSS . How can I define following material properties according Drude model in hfss.
ε=1-[(ωp)^2/(ω(ω+iγ))]
where for gold, ωp=1.37*10^16,γ=4.05*10^13,unit 1/s. when Freq wω=0.11Thz, ε=-114423*10^6+(2.32*10^7)i
When I edit Relative Permittivity=-114423, Dielectric Loss Tangent=(2.32*10^7)/(114423*10^6), the simulation completed with execution error on server.
Any solution to this negative permitivity problem in HFSS??
