Applications of multiscale waves concept iterative procedure

In this paper a multi-scale approach to design planar antennas and circuits is used in the scope of wave concept iterative procedure (W.C.I.P.). This wave formulation is improved for a full modeling of large-scale structures where connections are made through subdomains (layers) in the spectral domain. In the case of circuits integration the usually used elements - via holes and air bridge - are connections introduced to ease their integration in a circuit geometry between two and three dimensions, commonly named 2.5-D. A particular model is used to treat the electromagnetic behavior of these elements. For example, via-holes are treated with the longitudinal components, while air bridge are notably simplified by the introduction of "magnetic carpet". The simulation results presented are in accordance with the electromagnetic theoretical behavior of these connections.
