We have been interested in the localization of the energy carried by an electromagnetic wave of the TM type propagated at the surface of a cylindrical conductor coated with two dielectrics. The present study takes into account both the finite conductivity of the metal and dielectric losses. It is shown that it is possible to reconcile an excellent energy concentration with a very low attenuation of the wave.

Analytical Expressions

We have studied the electromagnetic microwave propagation of the HE11 mode on the surface of a cylindrical conductor coated with a dielectric and embedded in a second dielectric. The present study takes into account the finite conductivity of the metal and dielectric losses for the determination of precise analytical expressions of the attenuation factor and phase shift.

Analytical Expressions

We are studying the electromagnetic wave (magnetic transverse mode) propagation on the surface of a circular cross section metallic cylinder coated with one or several dielectrics. The method we use allows us to study not only the case of ordinary metals, but also the case of superconductor metals. We determine the precise analytical expressions (for any kind of metal) of characteristic quantities: attenuation factor and phase shift.
