We have studied the localization of the energy carried by an electromagnetic wave of the HE11 type propagated at the surface of a cylindrical conductor coated with two dielectrics. The influence of different parameters on the energy localization around the conductor is shown.

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.

An analogue of optical waveguide consisting of metallic nanoparticles chain was investigated using modified cylindrical dielectric resonators (DR) in the microwave range. The two lowest resonances of the DR correspond to the dipole and quadrupole modes of oscillations similar to plasma oscillations in spherical nanoparticles. It is shown that a waveguide consisting of seven resonators has high frequency selective properties and relatively low losses, if the resonances of quadrupole modes are used to form its bandwidth. The characteristics of the studied waveguide remain almost unchanged at its bending by 90. Cross-section of the main part of energy localization in waveguide is 5 times less than the length of the electromagnetic wave, which roughly corresponds to the optical waveguides based on plasmon oscillations in nanoparticles.
