A retro-reflection, polymer fiber cross section is fabricated using a tri-component fiber extruder. The fiber cross section is comprised of a series of right angles. The right angles are retro-reflection features that run the entire length of the fib

There is renewed interest in using rectennas (consisting of an antenna coupled to a rectifying diode) for energy conversion applications. Progress in nanofabrication has enabled nanoscale devices to be fabricated, such that "nanoantennas" exist that

Frequency Selective Surfaces (FSS) are comprised of periodic, geometric, metallic patterns that act like an array of horizontal antennas. They were originally designed as band-pass/band-block filters. Nanofabrication techniques allow for the realizat

Carbon nanotubes have been shown to exhibit light antenna behavior, such as polarization and length dependence, and enhancement of incident electromagnetic radiation at resonance. We study and model resonance effects from planar metallic nanoantennas

Nanocomposites made by adding nanoparticle reinforcement to polymers have been demonstrated to have significantly enhanced properties at relatively low levels of added reinforcement. The observed properties have in some cases been attributed to the s

Lenses and other transparent optical materials suffer rapid damage when subjected to blowing abrasive particulates. The time-scale of these impact event falls between typical scratch tests (less than 1m/s) and ballistic tests (100s of m/s) and has no

Extruded polymer fibers with submillimeter diameters are considered for tailored optical and near-IR properties. Retroreflection of light is demonstrated. Simulated and measured reflection spectra are compared and found to agree. Additional simulatio
A morphine versus saline discrimination was demonstrated using the Morris swim task as the behavioral baseline. The apparatus was a large circular pool filled with water made opaque by floating polypropylene pellets. Rats were placed in the tank in r
