摘要: Low-frequency (quasi-static) electromagnetic penetration of an aperture can be reduced by loading the with a conductive film or bonded-junction wire mesh. A quantitative analysis this phenomenon is carried out in paper for loaded circular perfectly conducting ground plane infinite transverse extent. Contact resistance between and rim taken into account. The quasi-static magnetic-field problem electrostatic field from which polarizabilities penetrant fluxes are determined shown to reduce solving single Fredholm integral equation. Exact (numerical) approximate (variational) solutions equation obtained, latter used represent simple analytical formulas equivalent circuits. These representations found quite accurate when contact not too large
