An Efficient Hybrid Method for Calculating the EMC Coupling to a Device on a Printed Circuit Board inside a Cavity by a Wire Penetrating an Aperture
نویسندگان
چکیده
An efficient hybrid method is developed for calculating the coupling to a device on a printed circuit board inside a cavity. The printed circuit board is connected to a wire or cable that penetrates through an aperture in the cavity enclosure. The method uses a combination of transmission-line analysis and a full-wave solver together with a decomposition of the problem into interior and exterior problems for maximum efficiency. Results are presented to verify the accuracy of the proposed method and to study the effects of cavity resonances on the coupling to a device inside the cavity.

We propose a hybrid scattering parameter matrix for concurrent on & off – board EMI analysis of mixed RF-Digital Circuits. To start with, we first consider on–board EMI effects on digital circuits, particularly on an inverter to show the vulnerability of digital devices to RF interference and investigate both system and device level upsets due to adjacent EMI sources on Printed Circuit Boards (...
متن کاملInfluence of the PCB Dielectric Material on the Coupling of PCB Traces to Enclosure Cavities
PCB structures like traces couple to the cavity field inside of an enclosure. It has been presented before that the coupling of a trace inside of a homogeneous cavity is caused just by its vertical segments on the trace ends. For an inhomogeneous cavity, consisting of a FR4 PCB layer and an air layer, we show that a trace couples along its whole length. The different coupling must be considered...
