Abstract

In this article, we apply the broadband Green's function for fast full-wave simulations of the radiated emissions from the printed circuit boards (PCBs) of irregular shape. Changes were made on the previous version that improve the computational efficiency and accuracies of the solutions. The improvements include imaginary wavenumber extractions for the acceleration of convergence of modal expansions without the need of high-order quadrature, and the fast-exact normalization of modes. Results of the radiated fields are illustrated over a broad frequency range up to 10 GHz and for irregular shaped PCB up to 4 in in sizes. The results are in good agreement with the method of moment for both the modal solutions and the radiated emissions. The results are shown to be more accurate than the previous version of broadband Green's functions with low wavenumber extractions. The significant computational efficiency makes this technique useful for electronic design automation to electromagnetic interference/electromagnetic compatibility applications.
