Description
-
In this study, we used scattering-scanning near-field optical microscopy (s-SNOM) to experimentally characterize several structures relevant to infrared (IR) antenna technology, by measuring the electric near-field strength as a function of positi...

Description
-
Nonpropagating excitations have been studied in 1-D and in 3-D, but not so much in 2-D. So, this thesis concerns 2-D nonpropagating excitations. In particular, we construct nonpropagating excitations confined to an annulus under a time-independent...

Photogrammetry is a measurement technique where 3D coordinate data and feature information can be extracted from 2D photographs or images. Length scale objects are calibrated artifacts placed into a photogrammetry scene which have precisely define...

Description
-
Artificially structured materials, which are treated as macroscopically homogeneous media, exhibit effective optical properties that can be altered by engineering the materials' intrinsic geometries at a scale much smaller than the probing electro...
