Dispersion and Polarization Control in Below-Cutoff Circular Waveguides Using Anisotropic Metasurface Liners

This article explores the application of metasurface (MTS) liners in perfect-electric-conducting (PEC) circular waveguides for cutoff manipulation and the introduction of controllable chiral properties. A dispersion equation is derived to predict the propagation characteristics of a circular wavegui...
