Analyse de la dispersion dans les guides d’ondes cylindriques

Abstract

Any wave passes through a substrate undergoes a modified form, the dispersion due to the interaction between the wave and the substrate requires a correction to recover the information transmitted through the material (when transmitting information through optical fibers the transport of electrical energy by the son ... etc..). Our goal is to first study the propagation of plane waves in solid media so that the propagation of waves with three-dimensional dispersion. The determination of propagation modes is done by specific equations describes the propagation in the guide and those specific to the constraints imposed by these guides. The resulting equation of Pochhhammer is solved by the numerical method of Newton, a correction of the dispersion is obtained by coupling the Pochhammer equation and spectral analysis of the signal.
