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