They are in essence the eigenmodes of a material system that correspond to oscillations, at optical frequencies, of the electron liquid with respect to the crystal lattice. It can be shown that ...

Abstract: This study presents a magnetic field-temperature-refractive index sensor based on surface plasmon resonance and photonic crystal fiber. The sensor integrates three independent sensing ...

A captivating optical illusion tests your observation skills. Initially, the image shows just one man on a secluded beach, but there's a hidden second man to discover. Try some other tips that ...

Structures that are periodic in one dimension are multilayer films and planar diffraction gratings. Structures that are periodic in two dimensions are patterned thin films and optical fibers with ...
