Zero-Index Platforms: Where Light Defies Geometry

Iñigo Liberal and Nader Engheta

Geometry-invariant effects in structures with near-zero permittivity or permeability could lead to deformable optical devices, and to new insights into unique light-matter interactions. Continue Reading

The Evolution Of Electric Light Bulbs
Imaged with the X-rays of Nikon's XTH225 CT system (left: Edison style incandescent light bulb, center: fluorescent light bulb, right: LED light bulb). In 2014, the invention of efficient blue light-emitting diodes (LEDs) was awarded the Nobel Prize in Physics. Subsequently, the United Nations declared the year of 2015 the International Year of Light and Light-based Technologies.
