Illyashenko L. Plasmon Resonances of Complex Nanostructures

Object - the processes appeared in nanostructures due to electromagnetic interaction of dispersive components, including periodic and no periodic structures of layered and solid nanoparticles. Aim - investigations of physical properties for propagation, scattering and absorption of electromagnetic waves by systems of dispersive nanoparticles with complex shapes. Methods - spectral method Furier-Galerkina for boundary integral equations; finite difference time domain method; finite element method; method of auxiliary sources; multiple multipole program. Results - method to search resonances in complex nanostructures is proposed and their dependence on size, shape, material properties and external media are established; method for parameterization of boundaries and method of analytical regularization are developed; techniques for balanced choice of all discretization parameters to insure the most accurate numerical solution are developed.improved model of the communication channel; developed by an address the response the method of information transmission. Implementation - SRW № 0110U002594, project INTAS №YSF 2001/2-11, project SNSF №200021_119976. Application - modeling of optical antennas, devices to control environmental pollution, medical diagnostics and therapy
