During the course of the thesis, we first carried out the analysis of certain methods of mesh refinement existing. This allowed us to identify phenomena of instability, it seems, new, associated with this type of schema.This is the reason that has led us to seek a new way to get around this difficulty. We then constructed and analyzed a new stable spatial-temporal grid refinement method applied to the simulation of wave propagation. We study alternatively the potentialities of such a method for the Maxwell equations and the wave equation, the ultimate goal imposed by the Gramat study center being to realize a codecomputer of mesh refinement for the Yee scheme in the case of 3 dimensions.This constraint has thus oriented us towards methods o...
