Quasicrystalline Structures with Narrow-Band Frequency–Angular Selectivity

Design methods in the reciprocal space allow one to obtain structures with desired properties. Quasicrystalline photonic structures, which ensure selective scattering of an electromagnetic wave incident on sample, have been designed. The maxima Fourier transform distribution permittivity are located along two arcs Ewald sphere, corresponds required wavelength and angle incidence. material has determined by transition real space. A structure a low dielectric contrast formed after binarization refractive index. theoretical analysis properties confirmed frequency–angular selectivity scattering. numerical calculations show possibility achieving effective absorption energy up 94% narrow frequency range interval angles incidence at materials 1.07.
