Larousse Khosravi Khorashad
NQPI NanoForum presents Larousse Khosravi Khorashad on “Theoretical and Computational Study of Optical Properties of Complex Plasmonic Structures” on Tuesday, Oct. 14, at 4 p.m. at Clippinger 259.
His adviser is Dr. Alexader Govorov, Professor of Physics and Astronomy. NanoForums are presented several times per semester and are sponsored by Nanoscale and Quantum Phenomena Institute.
Abstract: Research on plasmonics science and study of optical properties of photonic devices at the nano-scale have become extremely demanding over the past few decades owing to the introduction of innovative plasmonic devices and their vast applicability. The quest for light manipulation in metallic nanostructures has grown greatly due to the creation of novel optical devices for applications ranging from metamaterials and cloaking to optical sensing and plasmonic waveguides.
In this talk, I will present theoretical and numerical studies of complex nano-structures such as nano-ring geometries composed of metallic nano-spheres, and nanorods. We used the point dipole approximation, discrete dipole approximation, and finite element method for computational implementations. For each of the structures, we have obtained the plasmonic resonance modes. In the case of the nano ring, we have compared our results with experiment. Our simulation is in good agreement with the experimental measurements.
Future NanoForums will be held on Oct. 28, Nov. 4, Nov. 18, and Dec. 2.
