Experimental and theoretical investigation of RF absorption and reflection from preformed plasmas
Abstract
This report constitutes the final progress report for a program of experimental and theoretical research on the reflection, absorption, and scattering of VHF and microwave radiation from plasma-covered conductors. A principal goal of this research is to determine to what extent plasmas can be used to reduce the radar cross-section of highly RF-reflective objects. The major goals of this program were: to study RF absorption and reflection from a plasma-covered plane conductor to determine under what conditions the presence of the plasma can result in a significant reduction in the backscattered RF; to conduct such studies under a wide range of plasma (overdense and underdense) and RF (frequency, power density, and pulse duration) conditions; and to establish a solid theoretical foundation for the understanding of experimental observations.
