Diffusion Through Single And Double Layer Shields And Induced Voltages From Low Frequency Electromagnetic Environments

Warne, Larry K.; Basilio, Lorena I.; Coats, Rebecca S.; Jorgenson, Roy E.; Chen, Kenneth C.

The di ff usion through shells consisting of either a single conducting or double conducting layers are examined. Exterior drives resulting from Electromagn etic Radiation (EMR), Electromagnetic Pulse (EMP), nearby (indirect) lightning, and DC (low frequency) magnetic fi eldsareused. Boththeinterior fi eld and the induced voltage from a maximally oriented and sized single turn loop are estimated. It is shown that the loop voltage with the empty cavity bounds the case where the center region is excluded by a conducting object. The cases of interior magnetic and electric fi elds from an exterior magnetic drive and the interior electric fi eld from an exterior electric drive are both solved; the magnetic interior fi eldfromanexterior magnetic drive is the only case that results in a nonzero low frequency penetration.
