Propagation of ultrawideband pulsed radiation in conducting medium

A new method of solving the problem concerning a plane electromagnetic pulse scattering at the boundary of a conducting half-space has been discussed. Permittivity and permeability of a half-space dispersive medium are assumed not to depend on frequency. Application of nonseparable solutions of the Klein-Gordon equation reduce the problem of determining a field in a conducting medium. It has been shown that if the field at the medium boundary is determined then it allows to effectively calculate the field in the medium using an orthonormalized function system formed from linearly independent solutions of the Klein-Gordon equation. The scattered field is presented by expansions on orthonormalized system of Laguerre functions.
