IEMP Studies of a Dielectric-Filled Cavity: A Comparison of Experiment and Theory

The electromagnetic response of a dielectric-filled finite-length cylindrical cavity, exposed end-on at the Hermes II radiation facility, is experimentally and theoretically examined. Loop sensors were used to obtain azimuthal magnetic field related signals, and a dipole grid sensor was employed to acquire axial electric field related signals. The favorable comparison achieved between the experimentally obtained signals and the theoretically predicted results lends credence to the theoretical model developed.
