Analytic solutions of the problem of modulated impedance and dielectric structures excitation

This work presents the results of the analytic solution of problems of electromagnetic excitation of modulated impedance, dielectric and plasmon-polariton structures for different modulation laws of their construction parameters. The obtained results are of fundamental importance for the development of antennas, spatial filters, collimators and other elements of info-communication systems in a wide range of frequencies from terahertz to the optical range.
