Antenna And Wave Propagation Kd Prasad

[Gene Cryder]

RahulKumar completed a PowerPoint presentation on wave propagation under the guidance of Miss Arzoo. The presentation covered three main types of wave propagation: ground wave propagation, which uses the area between the earth's surface and ionosphere; sky wave propagation, which involves reflections from the ionosphere; and space wave propagation, where waves travel directly or after reflecting from the earth's surface through the troposphere.Read less

The e.m. wave propagation in a parallel-plate wave guide withone boundary corrugated and filled with uniaxial warmdrifting plasma has been studied. The dispersion relation and the field expressions for the TM-modes have been derived. The effects of the temperature and the drift velocity on the propagation modes have been studied in detail. The fast and the slow waves are greatly affected by the temperature and the drift velocity, whereas the wave guide wave is insignificantly affected. The effect of the corrugation has also been discussed. The dispersion relation of the TE-modes, in this case, has been derived and found to be same as that of the wave guide filled with free space.
