Abstract
Abstract The propagation of an electromagnetic field through a waveguide containing a biased semiconductor is being investigated. The presence of the bias establishes a current flow normal to the direction of propagation. The wave-current interactions are completely described by Maxwell's equations, the equation of motion, and the boundary conditions Propagation was found to occur with various degrees of attenuation, depending upon the characteristics of the structure and the semiconductor material. Reduction of the attenuation was found to be possible by either the reduction of carrier concentration, higher-order modes, carrier velocity, or geometry. Phase and group velocities were constant in the region covered by this study.
