Electromagnetic waves in a rectangular waveguide with metallic nanostructure

Abstract

The propagation of microwave electromagnetic waves in a rectangular waveguide with a multilayer metallic nanostructure is considered. The nanostructure is parallel to the waveguide axis with the layer planes perpendicular to the waveguide narrow wall. Using perturbation theory, adjustments for the complex propagation constant are derived. The frequency dependence of reflection and transmission coefficients is determined. Experiments on the measurement of the standing-wave ratio and transmission coefficient of millimeter waves propagating in a waveguide with a (Fe/Cr) n multilayer nanostructure are carried out.
