hi, I have studied the general expression for metamaterial as(adsbygoogle = window.adsbygoogle || []).push({});

n=√(εμ)

for dielectric relative permeability is one and we have

n=√ε,

but what would be the refractive index for magnetic material , by seeing symmetry I figure out as

n=√μ

will it be valid and we have Lorentz model for dielectric do we have some model for magnetic material.

thanks
