RADIATION FROM AN APERTURE IN A CONDUCTING PLANE COATED WITH A MOVING PLASMA LAYER.
Abstract
The radiation from a slot-excited infinite ground plane covered with a moving isotropic plasma layer is considered. Radiation patterns are given for a selection of frequencies and velocities parallel to the slot. It is found that layer motion produces a cross-polarized field in addition to changes in the normal stationary field. Both effects are largest for wave frequency near plasma frequency or velocity near velocity of light. In addition all radiation is attenuated over a range of velocities when wave frequency is less than plasma frequency. The attenuation range is lower for wave frequencies near the plasma frequency.
