Radiated emission from the slot of a slim cubical enclosure with multiple sources inside

Abstract

An efficient analytical model for the prediction of the radiated emission from the slot of a slim cubical enclosure with multiple sources inside is developed. We use this model to obtain the far field diagrams and the radiated power at the resonance frequencies, where emission becomes dominant. The radiated power from the slot of the enclosure depends on the number of sources, on their locations, amplitudes, and phase relations, even at low frequencies below the first resonance. We present the radiated power for some cases with one and two sources inside the enclosure. The analytical formulations allow to analyze the field distribution inside the enclosure and the radiated emission, which may be used to obtain placement and layout rules for critical components.
