Theory of modulated plasmon-polariton antennas

The theory of modulated plasmon — polariton antennas and the mathematical model of such antennas on the basis of periodically — inhomogeneous plasmon — polariton structure are proposed. The results of Matlab calculations of spatial distribution of a field of a plasmon — polariton antenna with surface impedance modulated by periodic sequence of impulse functions are given. The developed theory is suitable for calculating the parameters of the structure of reconfigurable nanoantena, supercollimators, interferometers and spatial filters.
