Optic pulse propagation in two dimensional graded-index waveguides can be described by (2+1)-dimensional nonlinear Schr(o)dinger equation with variable coefficients.
The geometry description of polarization is come up in 1892 and Poincare constructs the Poincare sphere.From then on Poincare sphere acts as a convinient way to express polarization of field.
Based on the special electromagnetic properties of topological insulator,we discuss theoretically the reflection of electromagnetic wave incident from dielectric to topological insulator,and focus on
The assembly of novel metal nanoparticles (NPs) into well-defined structures has attracted extensive research attention.When two metal NPs are closely spaced,their surface plasmon resonances (SPRs) wi
The recent experimental observation of optical extreme wave events in a microstructure fiber [1] has renewed the interest in the rogue waves,which initially describe a mysterious but calamitous phenom
