Fabry-Perot cavity with metal mirror on one side

I want to simulate a Fabry-Perot cavity, one mirror is dielectric mirror with multi-stack coatings, but another one is metal mirror. For metal mirror, I need to include Fresnel reflection losses and also attenuation due to imaginary refractive index.

I know there's a tutor example of Fabry-Perot cavity in COMSOL website, it's using geometric optics model, I already build a nice working Farby-Perot model with this model but it's with two dielectric mirror. Now I change one mirror to metal and include the complex refractive index of the metal, but the result is absolutely not right.

If geometric optics model could simulate my case, if yes, how can I correctly set metal mirror and include the losses. And if geometric optics model is not working, what model should I use? Thank you.
