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 ...

An international team of researchers including a team from the Center for the Advancement of Topological Semimetals (CATS), an Energy Frontier Research Center under the U.S. Department of Energy's ...

We often encounter nonlinear dynamical systems that behave unpredictably, such as the Earth's climate and the stock market. To analyze them, measurements taken over time are used to reconstruct the ...

Nonlinear optical crystals are a class of materials that exhibit unique properties when interacting with light. Unlike conventional optical materials, which respond linearly to the electric field of ...

• 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 ...
