Abstract
Shielding effectiveness and inner resonance of metallic frustum cone-like cabins illuminated by an intentional EMP are studied in this paper, with one coaxial feeding monopole antenna and some parallel slots on the cabin wall also considered. In our numerical simulations, hybrid FDTD method, integrated with surface mesh model, equivalent coaxial feed model, and thin wire model, are all implemented for handling such a complex three-dimensional (3-D) composite structure. Parametric studies are further carried out to show the shielding effectiveness and inner field resonance characteristics of the cabins with different geometries and the incident IEMP with different directions and polarizations.
