Multimode fiber endoscopes have recently been shown to provide sub-micrometer resolution, however, imaging through a multimode fiber is highly sensitive to bending. Here we describe the implementation of a coherent beacon source placed at the distal

Directionally reflective fiber arrays were woven with polymer fibers. Fiber cross sections produced using a tricomponent fiber extruder comprised standard circular as well as right angle retro-reflection features that run the entire length of the fib

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

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
