| Abstract: | In this paper, the characteristics of chiral nihility nonlinearities have been investigated theoretically. In the case of this medium, permittivity and permeability are equal to zero, regardless of the existence of nonlinear effects, which is due to the presence of cross-susceptibilities in chiral medium. We have made a study of hyperbolic secant (sech) pulse to define the influence of nonlinear chiral parameter on the propagation of an electromagnetic wave in chiral nihility media. Numerical results are given and discussed to confirm the characteristics investigated theoretically. |
