Theoretical investigation of enhanced sensing property in 1D TiO2/SiO2 periodic layers containing a defect layer of the nanocomposite with different radii of silver nanoparticles in the host liquid crystal

摘要

In this paper, we have theoretically investigated the effective dielectric permittivity of the nanocomposite (NC) layer of liquid crystal (LC) with silver nanoparticles at different radii using the Maxwell-Garnett model. The optical properties of a one-dimensional periodic structure (1DPS) of TiO2/SiO2 dielectric materials containing defect NC layer, (TiO2|SiO2)(3)|NC|(TiO2|SiO2)(3), with different radii of silver nanoparticles studied theoretically using the well-known transfer matrix method (TMM). The effective permittivity of NC for
