The technology uses simple gear such as a laptop and an antenna to disentangle the radar signals of foreign militaries, team of researchers says in recent paper.
The new observatory payload will help astronomers understand the nature of pulsars and black holes
Scientists say the device can launch multiple electromagnetic waves from a single antenna.
Named the 'microwave universal metasurface antenna,' this can dynamically, simultaneously, independently, and precisely control essential wave properties via software.
I'm currently writing a textbook on Electromagnetic Waves for my graduate optics students. I was reading up on zero refractive index materials for a chapter section and thought it would be fun to write a popularized account of their fascinating and counterintuitive properties! The past two decades have been a fascinating time to be an…
