Abstract:

The theoretical basis for describing both the process of electromagnetic radiation passing through a nonlinear film and its reflection from a thin-film coating with nonlinear properties is considered. The process of generating field harmonics at frequencies determined by the film properties and the characteristics of the incident signal is considered. This method of highfrequency correction of the signal spectrum, using a nonlinear film electrodynamic structure, will allow changing the shape of the pulse, which is transmitted along the waveguide from the generator. Thus, the proposed theoretical basis will determine the possibilities of controlling the shape of pulses that are transmitted along the waveguides without additional energy losses. It is established that the decrease in the duration of the pulse fronts leads to an increase in the energy of high-frequency components in the spectrum of the radiated signal, which allows an increase in the efficiency of focusing the field of most antenna systems. To realize such energy transfer to high-frequency components of the spectrum, it is suggested to add elements with nonlinear characteristics to the antenna.
