Contribution à la modélisation de structures planaires passives par l’approche dans le domaine spectral

Abstract

Various methods of electromagnetic modeling of the circuits in millimeters waves and microwaves were developed, their goal is to obtain a more precise electromagnetic model, which makes it possible to gain not only in computing times but also in precision. For transmission lines planar, simple layer or multi-layer of dielectric, the method approved and used is the spectral method, this method is employed according to a choice of basic functions, which satisfies the conditions of singularity on the edge of the conductor, and this choice is a key factor in the process of convergence. In order to reach a compromise between the precision and the time computing and characterize the currents, longitudinal and transverse, we proposed a new Basis Functions with Strongly Decaying Properties
