Shielding effectiveness, statistical characterization, and the simulation of a two-dimensional reverberation chamber using finite element techniques

A two-dimensional finite element model for both the transverse electric (TE) and transverse magnetic (TM) solutions inside a reverberation chamber has been presented. Tuner effects on the modal structure and the resulting statistics of the field distribution have been explored. The shielding effectiveness in a reverberating environment has been examined. Coupling shielding effectiveness for the TE results and replacement shielding effectiveness for TM results was presented. The reverberating environment provides additional insight into the shielding properties in a statistical sense. The shielding effectiveness of the TM structure for aperture coupling for several frequencies in a simulated reverberation environment was presented and compared to published and measured results. These results point to the development of a statistical model of shielding effectiveness. This model will form a critical component to the overall mechanism of upset prediction in digital systems.
