The Output Field of Curved Waveguides with a Cross-Section of Alternating Hollow and Dielectric Layers

Abstract

The aim of this study is to investigate the effects on the output field of curved (helical and toroidal) waveguides having a rectangular cross section made up of seven alternating hollow and dielectric layers. In this study, we will generalize the specific problem of a waveguide with the above cross section from a straight waveguide to both helical and toroidal shaped waveguides. We use a technique based on the inverse transforms of the Laplace and Fourier transforms for this purpose. This study clarifies how the cylinder radius and helix angle affect power transmission and output fields in this particular instance of a periodic cross section. The findings hold true in the microwave and millimeter-wave domains and can be helpful in applications involving helical or toroidal waveguides with periodic arrays of alternating hollow and dielectric layers. The results are true in the microwave and millimeter-wave regimes and can find utility in applications using a periodic array with alternating hollow and dielectric layers in a helical or toroidal waveguide.  According to the logical results we get in the output profiles, we can determine what are the logical parameters that should be taken before any experiment in the laboratory that we want to perform.
