Characterization of Optical Response of Dielectric Nano Antennas Having Complex Structures

Abstract

Characterized optical response of dielectric antennas have been complex structures have been studied. Electric and magnetic behavior of electromagnetic modes have been used with dielectric antennas. A quantum mechanical explanation due to inelastic interaction for electron beam was utilized. The calculation for integration for electron beams for orbital angular momentum was made. We have studied dimer of dielectric antennas of cylindrical and circular structures. The excitation components of vortex beam variation was found. For the purpose of study the spherical particles and cylindrical wires were considered of different materials. Electron energy loss spectra based on symmetry was used for the study. The magnetic properties were found due to variation of electron velocity. The characteristics of chirality was also found in the nanostructure of silicon. For controlling the light, the resonant electromagnetic modes of nanoparticles were used having greater refractive index. It was found that characterization of properties were due to resonant modes. The magnetic transition was found in bulk materials.
