The optical properties of multi-scale plasmonic structures and their applications in optical characterization and imaging

Creator:

Kuhta, Nicholas Anthony

Abstract:

The optical response of metallic structures is dominated by the dynamics of their free electron plasma. Plasmonics, the area of optics specializing in the electromagnetic behavior of heterogeneous structures with metallic inclusions, is undergoing rapid development, fueled in part by recent progress in experimental fabrication techniques and novel theoretical approaches....

Computational nanooptics in hyperbolic metamaterials and plasmonic structures

Creator:

Thongrattanasiri, Sukosin

Abstract:

This dissertation concerns several problems in the fields of light interaction with nanostructured media, metamaterials, and plasmonics. We present a technique capable of extending operational bandwidth of hyperbolic metamaterials based on interleaved highly-doped InGaAs and undoped AlInAs multilayer stacks. The experimental results confirm theoretical predictions, exhibiting broadband negative refraction response...
