Abstract:

This report addresses itself to one aspect of a simulator concept for simulating EMP in exoatmospheric regions by the incorporation of a spherical vacuum test chamber. Many important features affect the electromagnetic interactions of a space system with this type of spherical cavity. One of these is the problem of resonance. The report presents a complete parameter study of the resonant frequencies of a perfectly conducting spherical chamber with an inner spherically shaped impedance loaded damping structure. Frequency shifts are given for a wide range of damper location and loading. The resulting cavity damping is given for several lower order E and H modes.
