Multiple Scattering of Electromagnetic Waves by an Array of Parallel Gyrotropic Rods
We study multiple scattering of electromagnetic waves by an array of parallel
gyrotropic circular rods and show that such an array can exhibit fairly unusual
scattering properties and provide, under certain conditions, a giant
enhancement of the scattered field. Among the scattering patterns of such an
array at its resonant frequencies, the most amazing is the distribution of the
total field in the form of a perfect self-similar structure of chessboard type.
The scattering characteristics of the array are found to be essentially
determined by the resonant properties of its gyrotropic elements and cannot be
realized for arrays of nongyrotropic rods. It is expected that the results
obtained can lead to a wide variety of practical applications.Comment: 5 pages, 6 figure
