Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching ...

Nonlinear interferometers with correlated photons hold promise to advance optical characterization and metrology techniques by improving their performance and affordability. These interferometers ...

Metasurfaces, and in particular those containing plasmonic-based metallic elements, constitute an attractive set of materials with a potential for replacing standard bulky optical elements. In recent ...

Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

• Most problems are nonlinear from the get-go. • Simplified load-deflection cases can help explain nonlinear (structural) FEA. Which designers need nonlinear FEA and why? Actually, projects ranging ...

Long wires or distant wireless communications always garble the transmission. How can an engineer cure that distortion? Turns out, a lot of math and a little experience can work wonders. This author ...
