EMC CALCULATIONS OF ELECTRONIC-STRUCTURES IN NEARLY CLOSED CASINGS

The application of the general ''finite-integration-method'' for the n umerical solution of Maxwell's equations allows the calculation of ele ctromagnetic interactions between electronic structures and the surrou nding space regarding the shielding influence of a casing. This method is presented in a brief description together with the open boundary t reatment. The abilities of the program implementation are demonstrated in an example of a metallic chassis consisting of two separate parts with an electronic subsystem inside. The crosstalk is drastically incr eased for the spectral parts near the resonances of the casing.
