EMP Response of a Cavity: Field Generation within a Lossy Dielectric Cylinder Excited by a Radiation Pulse

A transient electromagnetic field problem is solved for a finite length cylindrical cavity bounded by perfectly conducting walls. The cavity is filled with a homogeneous lossy dielectric material. Analytic solutions for the relevant components of the electric and magnetic fields generated by an axially propagating current pulse are presented. Results obtained for various sample problems are discussed.
