An integral representation of solutions of the wave equation obtained earlier is studied. The integrand contains weighted localized solutions of the wave equation that depend on parameters, which are variables of integration. Dependent on parameters, a family of localized solutions is constructed from one solution by means of transformations of shift, scaling, and the Lorentz transform. Sufficient...
Two-dimensional model of a photoconducting emitter for the terahertz radiation excited by a femptosecond laser pulse is considered. Short-wave asymptotic formulas for electric fields of the emitter are presented. The contributions of both geometrical optics rays and effects of edges diffraction are taken into account.
