Investigations of the Influence of the Parametrical Modulation on the Propagation of Electromagnetic Waves in a Boundless Media

Using the integral equations method an analytical solution has been obtained for the problem of transforming a monochromatic wave by finite time rectangular recurrent pulse trains conductivity, permittivity and permeability of boundless homogeneous and isotropic medium. A simultaneous change of conductivity, permittivity and permeability hasbeen considered as well as changing only conductivity and permittivity for which the permittivity pulse train lags behind the conductivity pulse train by an arbitrary time shift.
