摘要

The problem of electromagnetic interference which couples to the interior of composite material shell enclosures is studied. Interference sources considered are a distant nuclear electromagnetic pulse, near-strike lightning, and direct-strike lightning. The electromagnetic properties of the composite material shell wall are simplified by assuming a constant bulk conductivity sigma. Several models for the coupling mechanism are analyzed including integral equation formulations, exact series solutions, and a diffusion coupling model. Several computer programs are presented to determine the interior fields over a large range of frequencies when the shell is modeled as an infinitely long two-dimensional cylinder of arbitrary cross section. A user-oriented interactive computer program is also described which is used to determine the response of circuits situated inside the shell. (Author)
