The directional polarization sensitivity of articular cartilage and meniscus is investigated by use of polarization-sensitive optical coherence tomography (PS-OCT) by varying the angle of incident illumination. Experimental results show that when the incident light is perpendicular to the tissue surface, normal articular cartilage demonstrates little polarization sensitivity, while meniscus dem...
We propose an ultra-wideband polarization-conversion metasurface with polarization selective and incident-angle insensitive characteristics using anchor-shaped units through multiple resonances. The broadband characteristic is optimized by the genetic optimization algorithm, from which the anchor-shaped unit cell generates five resonances, resulting in expansion of the operating frequency range...
An expression for the fraction of incident radiation transmitted by a right angle bend in a rectangular light pipe is derived. This expression is used to show that, in a planar light pipe structure with right angle bends, light attenuation is due only to reflection losses at the walls if the launching angle is 45 degrees .
