Final Review Report to U.S. Office of Naval Research from California Institute of Technology

Abstract

This report covers briefly the research performed under Contract Nonr 220(50) between September 1, 1963 and September 1, 1969. This con- tract was a continuation of a previous contract, Nonr 220(13), and in some cases carried through without interruption projects begun under the former contract. Equipment used under the former contract was continued under Nonr 220(50). The research was both theoretical and experimental and generally covered the following areas: Plasma wave resonances in spatially non-uniform plasmas Cyclotron and upper hybrid echo phenomena in plasmas Plasma wave echoes Cyclotron harmonic waves in plasmas Resonance cones in anisotropic plasmas Recombination radiation from forward biased p-n junctions Electro-optic effect Infrared absorption in gallium arsenide Modes in optical resonators with gain The results of the research were circulated in the form of O.N.R. Technical Reports and published articles in technical journals, lists of which appear in Sections III and IV of this report.
