Time Domain Transmission Coefficient for a Finitely Conducting Slab

The paper develops a simplified analytic solution for transmission coefficient of finitely conducting slab in time domain. To obtain the impulsive transmitting field, either for vertical or horizontal polarization, the relationship between the reflection and refraction on slab surfaces, as well as approximations to propagation loss is investigated. A numerical example of incident monocycle transmitting though a concrete slab using this technique is presented to illustrate the effective use of the method.
