Abstract: The moment method coupled with the uniform theory of diffraction is employed in this paper to simulate the electromagnetic shielding performance of an enclosure with apertures residing in a very large platform, in which the moment method is used to accurately model the enclosure with apertures, and the influence of the large platform is efficiently calculated by using the uniform theory of diffraction. These two methods are coupled through the tangential electromagnetic fields on the apertures of the enclosure. In this paper, the accuracy of this coupled method developed is validated, and we apply this method for simulating the shielding effectiveness with the sources inside/outside the enclosure. The simulation results show that this coupled technique is able to simultaneously model the effects of the smaller structures and the large platform on the total electromagnetic property. It further demonstrates that this coupled method is a very flexible and powerful technique for analysis of the electromagnetic compatibility problems with smaller objects mounted on a larger platform. © 2005 IEEE.
