One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of slightly misaligned periodic structures. This phenomenon, known as the moiré ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

QWP-based GP-SIDH architecture for artifact-suppressed full-color holography under broadband incoherent illumination: schematic overview (left) and video-rate phase retrieval with high-fidelity ...

Researchers have discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These so-called moir patterns can be tuned to look like periodic spots or even one ...
