Optical coherence tomography (OCT) has seen widespread success as an in vivo clinical diagnostic 3D imaging modality, impacting areas including ophthalmology, cardiology, and gastroenterology. Despite its many advantages, such high sensitivity, speed, depth penetration, OCT suffers from several shortcomings that ultimately limit utility a microscopy tool, pervasive coherent speckle noise poor l...

In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...

A rigorous theory is developed for light refraction by a photonic crystal PC with arbitrary lattice-type and surface orientation. First, the refraction of a planar wave incident upon a photonic crystal surface is analyzed. We rigorously prove the equal partition of propagating PC modes by a surface under a general condition. The concept of surface-orientation-dependent mode degeneracy has been ...
