effective dielectric constant of gold

[bel ami]

i want to calculate the effective dielectric constant of gold in anisotropic media
please help me how to solve my problem with effective medium theory

 

[enjunear]

Is the gold in suspension in some medium? I'm 99.99999% sure that gold, alone, is a conductor... not a dielectric.

 

[bel ami]

yes, this nano particles are in a host medium

for example substrate is glass

Look up Maxwell-Garnett relation as a starting point. Other than that as a simple case approximation, you will need to do EM simulation to extract effective parameters...

Have Fun

Possibily the bruggerman's model can be applied:

tnx a lot, i know that maxwell-garnet's model must be applied, but is there any codes for that?
