The framework for designing and fabricating a slow-light waveguide structure with conical Swiss roll metamaterial core at Terahertz frequencies has been carried out in this article. 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 the MATLAB programming tool verify extremely low group velocities in the aforementioned slab waveguides in the Terahertz 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 the CST simulation tool in Terahertz frequencies. Furthermore, a 2-D dispersion diagram fulfilled by CST and MATLAB validates highly electromagnetic field concentration as well as the presence of backward waves in the conical Swiss roll configuration.

用于慢光波导的锥形瑞士卷超材料应用

本文实现了在太赫兹频率下设计和制造具有锥形瑞士卷超材料核心的慢光波导结构的框架。在最早的工作中，已经为各向异性单负磁导率平板波导和各向异性超材料平板波导开发了基于麦克斯韦方程组的理论背景。随后，由 MATLAB 编程工具实现的仿真结果验证了上述平板波导在太赫兹频率范围内的极低群速度。体积圆锥瑞士卷超材料已被提议作为慢光波导的实际成就。已使用 CST 模拟工具在太赫兹频率下研究了所提出的锥形瑞士卷超材料中电磁波的色散特性。此外，由 CST 和 MATLAB 实现的二维色散图验证了高度电磁场集中以及锥形瑞士卷配置中反向波的存在。
