Absorption loss

[88888888]

How to calculate the absorption loss for an extended-hemispherical Si lens? (permitivity=11.7,resistivity=2000 ohm-cm,lens diameter=12.7mm, lens volume=828x10^-9(m^3),f=90GHz)

Article seems to be applicable.

By the way, I have no idea how to do the calculation myself. Good luck.
