Angle of incidence, RF modul, Comsol 4.2a

I have issue. I have one metal block on substrate, and I want to illuminate it but at some angle (picture).
One half sphere is substrate, one half air.
Now I want to apply x polarization, scattered field.
I have two cases, first when substrate is also air, and second when substrate is glass (with index refraction ns).
In the case when substrate is air I applied equation: E0*exp(-j*(emw.k0*x*sin(phi)+emw.k0*z*cos(phi)).
In the case when substrate is glass I applied equation: E0*exp(-j*(emw.k*x*sin(phi)+emw.k*z*cos(phi)).
Or maybe in second case I have to write:
Tell me please for any of these equations are they correct.
Thank very much in advanced.
