Abstract

The present discussion is concerned with the study of transient phenomena due to localized sources in a bounded dispersive medium, with emphasis on the propagation of surface waves. To accommodate these features, the configuration of a magnetic line source parallel to the gyrotropic axis in a cold magnetoplasma has been chosen, with a perfectly conducting plane providing the bounding surface. After a formulation of the solution in integral form, the asymptotic considerations in Part I of this paper are applied for calculation of the transient behavior of the incident, reflected, and surface wave constituents. Properties of these source-excited waves are discussed and are compared with the corresponding response to plane wave excitation. By comparison with an exact solution, some observations are made concerning the accuracy of the asymptotic approximations.
