A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many colors. The trick combines two geometric phase effects so each spin channel ...

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

The research group led by Professor Yijun Feng and Professor Ke Chen from Nanjing University reports a hybrid-phase strategy that unlocks broadband achromatic wavefront control for both circular ...

With the introduction of adaptive deep brain stimulation (aDBS) for Parkinson's disease, new questions emerge regarding who, why, and how to treat. This paper outlines the pathophysiological rationale ...

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

With engineered microstructures, metamaterials enhance stealth capabilities, enabling advanced wave manipulation for improved military platform invisibility.
