The High Efficiency Multimode Imager (HEMI) is an instrument currently under development for the purpose of detecting, locating, and spectroscopically characterizing gamma-ray emission sources at long-range standoff distances. The instrument design consists of multiple planes of relatively large-volume, good-energy-resolution detector modules configured for combined coded aperture and Compton scatter...
In an effort to optimize the spectroscopic performance of large volume Cadmium Zinc Telluride (CZT) radiation detectors grown by the Traveling Heater Method (THM), especially for higher energy gamma detection applications, bulk material and pixellated detector performance of THM CZT crystals at 15mm-thick and 10mm-thick were compared to that at 5mm-thick. We demonstrate that the outstanding performance...
Integrated plasmonic devices may be isolated using plasmonic Bragg reflectors (PBRs). Systematic experimental characterization shows optimal reflection for three PBR layers, 45 nm deep. Isolation between series of nanohole array structures using PBRs is demonstrated.

Quasicrystal arrays show a rotationally symmetric diffraction pattern that can be oriented with the polarization. A comprehensive electromagnetic theory agrees with the observed transmission spectrum and diffraction, and it shows near-field hot-spots.
Plasmonic Bragg reflectors (PBRs) enhance extraordinary optical transmission (EOT) through arrays of subwavelength apertures. Here, we characterize PBRs with variable line depth, number of holes in the array, and number of lines. The experimentally determined optimum depth of 45 nm and the EOT enhancement saturation for only three PBR lines is discussed in terms of the surface plasmon polariton skin...
We present plasmonic Bragg reflectors for increasing the extraordinary optical transmission through periodic arrays of subwavelength apertures in a metal film. The increase in transmission arises by preventing loss at the edges of the array. The plasmonic Bragg reflectors have periodicity of half the usual array's periodicity. Nano-hole arrays flanked thus by reflectors exhibited double the transmission...
