Radio Wave Absorption: Formula & Pressure/Temp Dependence

[sid_galt]

Is there a formula to determine how much absorption of a radio wave will occur in a plasma?

Does radio wave absorption depend on the pressure and temperature aside from the electron and ion density?

The answer depends on many factors such as whether the plasma is uniform or magnetized and how intense the impinging wave is. Perhaps you could provide more detail about the problem you're trying to solve.
