      [Abstract]: The transient field excited by an impulsive line source near a dielectric half space is solved and analyzed via the spectral theory os transients (STT). In this formulation, the field is described as a spectral integral comprising an angular superposition of time-dependent plane waves. Via function-theoretic thechniques, this STT integral is evalluated exactly, giving rise to closed-form field solutions which agree with those derived via the Cagniard-de-Hoop technique. The STT formulation however provides a flexible framework that could also be used for wave fields in inhomegeneous media or for collimated wavepackets. We use the reflected and transmitted fields, including the pulsed evanescent wave and the head-wave contributions.
