The pulsed electromagnetic radiation from a two‐dimensional line source in a lossless two‐media configuration is investigated theoretically. The author's modification of Cagniard's technique is used to derive closed‐form expressions for the electromagnetic field components anywhere in the configuration. Numerical results are presented pertaining to the incident, the reflected, and the transmitted wave for different positions of the source and the observer, as well as for different contrasts of the two media. Also, the corresponding total‐field plots are shown. In an appendix, the modified Cagniard contours pertaining to a lossless N ‐media configuration are discussed and some two‐media modified Cagniard contours are shown.
