We present an all-dielectric resonant metasurface with full 2π phase control at microwave frequency. Through numerical simulation, we show that by overlapping its magnetic and electric resonances, the ...

For years, scientists have suspected that stars can meet their doom by a one-two punch of back-to-back explosions — but ...

In this work a metasurface able to provide anomalous refraction of a plane wave has been proposed. Unlike other designs, our structure is made of just one type of geometry, what makes the design very ...

The shattered star at the center was once a white dwarf, a stellar ember no larger than Earth, yet almost as heavy as the Sun ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” ...

This is the first evidence for a white dwarf exploding not once, but twice. The discovery could shed new light on how some ...
