Dispersion characteristics of hybrid surface waves at chiral-plasma interface

Abstract

The theoretical analysis of hybrid surface wave propagation at chiral-plasma planar interface is presented in this manuscript. The dispersion relation is obtained for the proposed structure by applying boundary conditions at the chiral-plasma interface. The characteristic of hybrid surface wave can be tuned by changing the plasma frequency, plasma collisional frequency, and chirality parameter. It is shown that phase constant , attenuation or propagation loss and propagation length are dependent on plasma and chiral parameters. The effect of plasma frequency, plasma collisional frequency, and chirality parameter on the normalized phase constant , attenuation constant, and propagation length are presented computationally. Moreover, to verify the surface wave's condition normalized filed distribution is also presented. The present work may have potential applications in chiral and plasma-sensing based waveguide and enantiomeric sensing devices.
