摘要: The common-mode current induced on cables attached to printed circuit boards can be a significant source of radiated emissions. Previous studies have shown that coupling from electric and magnetic field sources effectively modeled by placing equivalent voltage between the board cable. amplitude these estimated using closed-form equations; however, estimates emissions board-cable geometries required full-wave simulations, simulation results depend exact cable length placement, which are not normally fixed during testing. This paper develops equation estimate maximum fields driving relative an over ground plane. is evaluated for various comparing calculated simulations. radiation expression generally predicts peak within few decibels sizes lengths.
