Conical Swiss Roll Metamaterial Application for Slow-light Waveguides

Abstract

The framework for designing a slow-light waveguide structure with Conical Swiss Roll Metamaterial at THz frequencies have been carried out. In the earliest work, theoretical backgrounds based on Maxwell’s equations have been developed for anisotropic single-negative permeability slab waveguides and anisotropic Metamaterial slab waveguides. Subsequently, simulation results fulfilled by MATLAB programming tool verify extremely-low group velocities in the aforementioned slab waveguides in THz regime frequency. A volumetric Conical Swiss Roll Metamaterial has been proposed as a practical achievement for slow-light waveguides. Dispersion characteristics of the electromagnetic waves in the proposed Conical Swiss Roll Metamaterial have been investigated using CST simulation tool in THz frequencies. Furthermore, two-dimensional dispersion diagram drawn by CST and MATLAB validates highlyelectromagnetics field concentration as well as the presence of backward waves in the Conical Swiss Roll configuration.
