Statistical shielding effectiveness - a modal/moment method approach to characterize the average shielding effectiveness over a wide frequency range including resonances

This brief work emphasizes the application of numerical methods to explore the ideas related to shielding effectiveness from a statistical view. An empty rectangular box is examined using modal/moment methods. Fields statistics will be obtained by using frequency stirring borrowed from the ideas connected with reverberation chamber techniques. The work is intended to provide a means of representing the shielding effectiveness of structures that are large as compared to a wavelength in a simple way - an attempt at creating a nomograph for shielding effectiveness.
