Abstract

We analyze dielectric liner and periodic planar guides for moderate power, low voltage sources of millimeter waves. The analysis shows that optimum gain utilizing thin, high dielectric constant liners can be obtained at lower voltages (< 75 keV). A companion analysis of periodic gratings shows that large depth gratings (0.75<p/d<5.0) allows a comparable millimeter range spatial wave growth (2-5 dB/cm) at moderate beam voltages. We present results of analysis for the Streaming Beam Experiment (SBX) which is under construction at the University of Wisconsin.
