If an electromagnetic wave is transmitted at 127MHz (roughly) from space, the permittivity of the plasma is 0 (and negative for frequencies below 127 MHz - quickly attenuating the signal). But there is nothing to mathematically indicate if the wave is reflected or the energy absorbed by the plasma. Is the signal reflected or absorbed and what determines this? Can it (determination of absorption or reflection) be mathematically modeled?
