This is the Crab Pulsar, and within its radio pulses is a strange signal that has puzzled astronomers for years. Called the ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to ...

A recent paper explores the multiplexing of infinite functionalities using a single metasurface, leveraging coherent wave ...

The two interfering sources must emit the light of the same wavelength and time ... The fringes of different interference patterns will overlap. The two interference waves must be propagated along the ...
