Microwave Emission from Plasma Electromagnetic Radiation: A Phenomenological Approach
Abstract
The macroscopic approach to the problem of equilibrium radiation from plasmas is treated based on the theory of electrical fluctuations and thermal radiation proposed by Rytov. The basic ideas underlying this general theory as well as the connection with other known theories of equilibrium radiation are discussed. The electromagnetic formulation of this theory is then presented. In particular the transition between the microscopic and the macroscopic electromagnetic equations is demonstrated and the connection with Rytov's equations is made. The statistical aspect of the problem is formulated and the general expressions for the time and space averages of the intensity of radiation is presented. A general method for solving problems of equilibrium radiation is outlined. A detailed derivation of this solution as well as an alternate solution in terms of the power absorptivity of the cylinder is given.
