Reflection of Optical Signals on the Border of Heterogeneous Chiral Layer with Dispersion

An oblique incidence of electromagnetic pulses of a special form on a flat inhomogeneous chiral layer with dispersion and absorption had considered. The frequency of the harmonic carrier for pulses of a special form: Gaussian, giant and triangular is equal to the resonant frequency of the material medium with dispersion. The solution in the form of the 4 × 4 Cauchy matrix, obtained using the Wentzel-Kramers-Brillouin approximation, is used to calculate the waves in an inhomogeneous chiral layer. The effect of chirality on cross-polarization upon reflection is shown. The effect of the dispersion of optical properties, as well as the dispersion of the chirality parameter of the medium on the shape of the envelope of the signals for different angles of incidence, is shown.
