Radio Frequency (RF) Propagation Along Single Cylindrical Conductors

摘要

This report examines the transmission of 10 GHZ radio frequency (RP) waves among single cylindrical conductors. Intent is to determine attenuation as a function of distance and conductivity in order to enhance understanding of phenomena related to attachment and transmission of RF to a laser generated plasma filament(s). Attenuation is shown to be highly dependent on conductivity as well as diameter of conductor in some cases providing significant gain over free space propagation. This increase in gain demonstrates promise of a single cylindrical conductor as a transmission mechanism. Data is shown to be relatively consistent with Finite Difference Time Domain modeling for the case of a single cylindrical conductor and open ended waveguide.
