Abstract: This paper proposes a new hybrid method called MS-GEC/PO. This method is based on the coupling between the multi-scale combined to generalized equivalent circuit method (MS-GEC) and the hybrid approach MoM-GEC/PO (MoM-GEC method coupled to Physical Optic method). The MS-GEC method, in its new formulation based on local modal operators, can reduce considerably the requirements (CPU time and memory resources) especially when the number of scales increases. However, the MoM-GEC/PO can reduce these requirements because it is based on a single test function permitting an important reduction of the manipulated matrices size. Consequently, applying the new hybridization MS-GEC/PO, we can take the advantageous of both of these methods assuring a multiple gain in requirements. In this paper, we present the new considered hybridization and we validate it on an example of application. The obtained results are in agreement with the MoM-GEC method.
