Download or read book Electromagnetic Properties of a Plasma-covered Antenna written by Daniel J. Jacavanco and published by . This book was released on 1965 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antenna patterns (E-plane) of an X-band horn mounted in a ground plane and covered by a plasma slab were measured. A pulsed plasma was produced by capacitor discharge in a rectangular pyrex container of 6 in. x 2 in. x 24 in. i.d. Microwave interferometer measurements of the electron density were made at 9 and 35 Gc. Antenna patterns are presented which show a sharp decrease in radiated power at certain angles corresponding to the 'optics critical angle'. Good agreement is obtained for the movement of the optics critical angle with plasma density. (Author).
