In this study, numerical analysis has been carried out at plasma loaded uniaxial chiral slab waveguide. The formulation is based on differential form of Maxwell's equations and characteristics equation is obtained by employing boundary conditions at uniaxial chiral-plasma-uniaxial. Two cases of uniaxial chiral media i.e., axial permitivity grater than tranverse permitivity and axial permitivity less than tranverse permitivity are discussed to explore the characteristics for proposed waveguide structure. The influence of collsional frequencies, plasma frequencies, chirality and core width of waveguide on normalized propagation constant and propagation are analyzed. Numerical results indicate that physical parametrs of isotropic plasma (collisonal frequency and plasma frequency), chirality and core width play pivotal role to tune the normlized propagation constant, propagation length band gap and cut-off frequency in certain frequency range. The extraordinary traits of uniaxial chiral and plasma medium offer a wide range of research and development possibilities in diverse areas of optoelectronics.
