Electromagnetic wave propagation and source radiation in space-time periodic media


Elachi, Charles (1971) Electromagnetic wave propagation and source radiation in space-time periodic media. Dissertation (Ph.D.), California Institute of Technology.


The electromagnetic wave equations for the fields, potentials and Hertz vectors are derived and a Lorentz gauge is given for space-time dependent media. Electromagnetic wave propagation, electric and magnetic dipole radiation, and Cerenkov and transition radiation in sinusoidally space-time periodic dielectric, plasma and uniaxial plasma are studied and numerous radiation patterns are given. A special radiation effect in the uniaxial plasma is investigated. Finally the study is extended to general space-time periodic media (i.e., [epsilon] = [epsilon][subscript o][epsilon][subscript r] [1 + [epsilon][subscript 1] f(Kz - [Omega]t)] where f([Epsilon]) is a periodic function).
