Аннотация: Abstract: An analog of an optical waveguide in the form of a chain of metallic nanoparticles has been investigated using modified cylindrical dielectric resonators in the microwave band. Similar to the plasma oscillations in spherical nanoparticles, the two lowest resonances of the dielectric resonator correspond to the dipole and quadrupole oscillatory modes. It is shown that a waveguide consisting of seven resonators exhibits high frequency selective properties and relatively low loss if the resonances of the quadrupole oscillatory modes are used to form its passband. The characteristics of the investigated waveguide remain almost unchanged at its bending by 90°, and the cross section of localization of the main part of the energy propagating in the waveguide is smaller than the electromagnetic wavelength by a factor of five, which approximately corresponds to the optical waveguides based on plasma oscillations in nanoparticles. © 2019, Pleiades Publishing, Ltd.
