Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for decades. The process, known as time reflection, causes a wave to retrace ...

Scientists have been unable to confirm the existence of time reflection due to the amount of energy required to create a ...

The "cloaking technology," which manipulates electromagnetic waves to avoid detection by radar or sensors, has now been ...

What do Harry Potter's invisibility cloak and stealth fighter jets that evade radar have in common? They both make objects ...

We suggest that there should be a minimum electromagnetic radiation frequency in the Hubble sphere and that this seems to be directly linked to the Hawking Temperature and our recent discovery that ...

Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time ...

Radio over fiber transports RF signals via optical fiber, enabling low-loss distribution for wireless networks, radar systems, and radio astronomy applications.

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...
