Abstract
This study explores the behavior of the SPPs mode propagating along a plasma-LiF-plasma planar waveguide structure. Real and imaginary parts of LiF permittivity are analyzed in the THz frequency range. Furthermore, the dependence of effective mode index, propagation length, permittivity of LiF, phase velocity and normalized propagation for different collisional frequencies, plasma frequencies, and LiF thickness are analyzed in the THz frequency spectrum. Based on the calculated numerical results, it is reported that different characteristics of electromagnetic surface waves are strongly influenced by physical parameters of isotropic plasma and LiF permittivity. The proposed waveguide scheme can be used in plasmonic sector for the development of novel plasma and LiF-based nano-plasmonic devices and making it ideal for high-performance optical communication and sensing applications 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.
