Abstract
Propagation of transient electric and magnetic (TEM) pulses in nonstationary,
linear, homogeneous, and isotropic dielectric and magnetic materials is
investigated using an exact wave splitting. Key intrinsic properties are the
index of refraction and the relative admittance, which are both temporal integral
operators with kernels that depend on two time variables. In addition, the
Sommerfeld forerunners in dispersive nonstationary materials are derived. A
numerical example — a single-resonance Lorentz model with time-dependent
plasma frequency — is presented.
