Ray-optic theory is applied to a collisionless strongly deviating turbulent plasma to determine the microwave power transmitted through the plasma. The transmission coefficient is calculated for two cases: (1) The `Fraunhofer' region, in which the receiving aerial is at a quasi-infinite distance and (2) the `Fresnel' region, in which both aerials are close to the plasma boundaries. The Fresnel region results apply to most experimental installations, and an example of their application to ZETA measurements is given. The main feature of the transmission coefficient is its strong dependence on the turbulence parameters, but subsidiary directional effects may be of practical interest. The deduction of the mean square ray deflexion from the turbulence parameters is made possible by a reduction of the parameters followed by an application of a previous ray-theory work. |
