A New Approach of Almost Periodic Lumped Elements Circuits by an Iterative Method Using Auxiliary Sources

Nowadays, met materials with lumped or distributed elements are emerging and it is necessary to develop new techniques based on the following principles. The approach should be global and have to be formulated according to the existing classic formulations. In fact, the Wave Concept Iterative Process (WCIP) is systematically used in such application. On the other hand, the periodic medium can have some cells with localized defects that are supposed to be almost periodic. Such structures are studied based on the introduction of auxiliaries’ sources. The study is devoted to the study of one dimensional then bi dimensional medium. Simple diffraction phenomenon supports the usefulness of the proposed new approach.
