ELECTROMAGNETIC PROPERTIES OF DRIFTED SEMICONDUCTOR PLASMAS. PART II. ENERGY, POWER, AND ACTIVE PROPERTIES,
Abstract
The report deals with energy and power relations in semiconductor materials with drifting majority carriers. Active properties are discussed on the basis of the time-average electromagnetic power density of plane waves characterized by real frequencies. The report emphasizes the effect of drift current, which causes the conductance to differ from the conductivity. The conductance matrix, evaluated from the dynamic equations, is used to establish simple criteria for active behavior. These criteria express the active properties in terms of the phase velocity relative to the drift velocity. The different dissipation characteristics of irrotational and solenoidal waves are emphsized, and examplified by the carrier waves and electromagnetic waves in a semiconductor. With two waves propagating in the medium, the active properties are modified due to the cross-power arising from interaction between the waves. The various effects arising from the interaction are discussed. (Author)
