Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, ...

Traditional computational electromagnetics (CEM) methods—such as MoM, FEM, or FDTD—offer high fidelity, but struggle to scale ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...
