摘要

在本手稿中，我们对等离子体-金属平面界面进行了数值研究，以探索表面等离子体极化子（SPPs）的一些特征。基于电磁波理论，我们推导出了一个频散关系。详细分析了张量介电常数参数对有效模式指数和传播损耗的影响。数值结果表明，环等离子体参数，即手性、回旋频率和等离子体频率，对太赫兹频谱中的有效模式指数和传播损耗有显著影响。所展示的环等离子体-金属 SPPs 结果为在太赫兹频率范围内制造紧凑型纳米光子器件提供了新的可能性。

Generation of Surface Plasmon Polaritons (SPPs) at Chiroplasma-Metal Interface

In this manuscript, numerical investigations at the chiroplasma-metal planar interface have been performed to explore some features of surface plasmon polaritons (SPPs). Based on the electromagnetic wave theory, we derive a dispersion relation. The effect of tensorial permittivity parameters on effective mode index and propagation loss is analyzed in detail. Numerical results show that chiroplasma parameters, i.e., chirality, cyclotron frequency, and plasma frequency, have a significant impact on effective mode index and propagation loss in the THz frequency spectrum. The presented results of chiroplasma-metal SPPs provide new possibilities to fabricate compact nanophotonic devices in the THz frequency regime.

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
