Fundamental Field Equations in a Temporally Dispersive Medium,and wave propagation in a homogeneous, isotropic, locally linear, temporally dispersive medium that occupies all space is presented. The general frequency dependence of both the dielectric permittivity and the electric conductivity is included in the analysis so that the resultant field equations ap

Analysis of the Phase Function and Its Saddle Points,temporally dispersive medium, it is necessary to first determine the topography of the real part X(ω),θ) of the complex phase function φ(ω,θ), defined in (4.37), in the complex ω-plane. In particular, the location of the saddle points of φ(ω, θ), the value of φ(ω, θ) at these points, and the regions

Evolution of the Precursor Fields,is presented in this chapter begins with an examination of the exact field behavior for times . such that . = ./. < 1, for a fixed observation distance .. By applying the method . used to treat the step-function modulated signal, it is shown here that for fields with the initial envelope
