## Abstract

Radiation phenomena are central problems in many topics such as EMP (E.M. Pulse), EMC (E.M. Compatibility) and EMI (E.M. Interference), inverse scattering, microwave imaging and radar target identification. Because of that the analysis of radiation problems in time domain is of increasing practical interest. In these problems we have to deal with interacting objects of arbitrary shape separated by large distances in free space or in open site. In this contribution we present a novel hybrid Transmission Line Matrix-Integral Equation (TLMIE) method in which the efficient Integral Equation method (I.E.) is combined with the very flexible Transmission Line Matrix (TLM) method, for the solution of radiating problems. This method works in time domain for efficient solution of transient interferences. For the analysis of many radiation problems the Method of Moments (MoM) is a common tool. Its efficiency is related to the geometry of the given structure. Especially in the case of different combined dielectric structures the Method of Moments presents increasing analytical and computational problems. On the other hand the TLMIE Method is applicable very easily to a large variety of problems for structures of nearly arbitrary shape. We apply our hybrid method on a typical EMC problem of the radiation from apertures in metallic enclosures, fixed by a dielectric slab. The numerical results of the TLMIE method are then compared with results obtained by the pure TLM method.
