AI Technical Summary
Existing technologies for solving the electromagnetic coupling response of electronic systems under electromagnetic radiation, especially at high frequencies and with complex structures, suffer from low computational efficiency and insufficient accuracy, and cannot accurately determine the coupling terminal response under the worst operating conditions.
A system-level electromagnetic coupling fast analysis method based on reciprocity is adopted. By modeling the cable coupling model of the electronic system as a multi-port antenna system, the Fast Fourier Transform and the antenna reciprocity theorem are used, combined with the frequency pointer and impedance matrix, to calculate the spectrum and time-domain sequence of the induced voltage, so as to achieve efficient solution of the omnidirectional and fully polarized coupling response.
It significantly improves computational efficiency, reduces computational overhead, ensures the accuracy and comprehensiveness of results, and can objectively determine the worst-case coupling terminal response of an electronic system, making it suitable for complex electronic systems.
