Protective Properties of a Generic Missile Enclosure to Different Electromagnetic Influences

Electronic components and subsystems of a time critical system (e.g. an aircraft) must be highly unsusceptible to electromagnetic influences. In order to predict the immunity of a generic missile (GENEC) against electromagnetic influences, not only the electronic system but also the enclosure has to be taken into consideration. Assuming a sufficient conductivity of the metallic enclosure, apertures in this enclosure effect a substantial reduction of the shielding effectiveness. The shielding properties of the generic missile could be investigated by means of a metallic hollow cylinder equipped with different apertures. Numerical simulations and measurements of this cylinder will be carried out and analyzed.
