Abstract
This paper describes a new hybrid unfamiliar model of apertured enclosure with lumped resonator networks and Kron-Branin (KB) method. It acts as a radiated EMC model of rectangular cavities regularly used in aeronautics and spaces electronic systems. The KB equivalent graph combining the low- and high-frequency (LF/HF) EM radiations, is established based on the enclosure geometry. The tensorial expression of the enclosure impedance metric translated from the graph is proposed to estimate the shielding effectiveness (SE) at any point inside the enclosure. The proposed hybrid model is applied to a rectangular enclosure with rectangular aperture illuminated by EM plane wave bandwidth from very LF and the enclosure first TM mode.
