Information × Registration Number 0210U000193, 0108U004877 , R & D reports Title Electrodynamics of nonchiral focusing systems on basis of resonant and chiral elements popup.stage_title Head Prosvirnrn Sergey Leonidovich, Registration Date 27-01-2010 Organization Institute of Radio Astronomy National Academy of Sciences of Ukraine popup.description2 The effective algorithm for solving problem of diffraction by planar periodic structures in optical range was offered. «Trapped mode» resonances in optical structures with asymmetric elements were analyzed. The new type of nano-device ("lasing spaser") was proposed. The possibility of its practical realization was shown theoretically. The polarization characteristics of electromagnetic waves scattered by structure with chiral elements in optical range were analyzed. The frequency characteristics of electromagnetic waves transmission in thin metal layer with the periodically located holes which size is less than half-wavelength were investigated. The diffraction characteristics of double-layer structures with resonance elements were researched. The possibility of creation of a new class of polarization converters and polarization-selective filters working in regime of nonspecular reflection of electromagnetic waves with the controlled characteristics was shown. The local sources field interaction with double periodic planar structures in frequencies close to “trapped mode” resonance was investigated. The possibility of electromagnetic field focusing by using of a two-dimensional photonic crystal was demonstrated.
