Scientists Discover Strange "Narwhal" Waves That Trap Light Beyond Known Limits Physicists at Peking University have made a major breakthrough by formulating the singular dispersion equation, which allows for extreme light confinement in purely dielectric materials without relying on metals and their inherent energy dissipation.
This advance has far reaching implications, particularly when considering the long standing challenge of miniaturizing photonic devices.
Conventional wisdom held that shrinking photonic components would be a daunting task due to the uncertainty principle linking light's confinement to its wavelength.
