Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...
Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside ...
Teachers advise students to focus first on high-weightage chapters and revise them thoroughly to maximise scores.Neeraj Kumar Singh, PGT Physics, Sunbeam School, Ballia, Uttar Pradesh, emphasizes that ...
Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...
Ultrafast shaping of exciton-polariton condensates enables applications for classical and quantum logic devices and provides insights into the physics of nonequilibrium quantum condensates in ...
To those who think the practice of reading tarot is an occult art reserved for spook sessions, let’s get this out of the way: It isn’t. Like therapy, meditation, and advice from friends, tarot is ...
About 2,500 years ago Greece was one of the most important places in the ancient world. The Greeks were great thinkers, warriors, writers, actors, athletes, artists, architects and politicians. The ...
Abstract: Fermat’s Principle, or the Principle of Least Time, is used to computationally model common optical phenomena, including reflection, refraction and dispersion through a prism. Fermat’s ...
Abstract: For large planar array antennas, one key performance metric is the active reflection coefficient of each radiating element. However, verifying this coefficient through measurement typically ...
