Blocking radio waves and electromagnetic interference with the flip of a switch Researchers report dynamic control of electromagnetic wave shielding using MXene materials Date: January 16, 2023 ...

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 ...

Scientists demonstrate time reflection of electromagnetic waves in a groundbreaking experiment The discovery establishes the foundations for revolutionary applications in wireless communications ...

Electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively, and change course. This allows our eyes to see a reflection or echo of the original input.

At such an event, a portion of the wave is time reversed, and its frequency is converted to a new frequency. To date, this phenomenon had never been observed for electromagnetic waves.

The ability to detect radiation across the electromagnetic spectrum is vital for astronomers, as only a small fraction of the light in the universe comes in the visible part of the spectrum.

To the left of the electromagnetic spectrum are radio waves, the lowest frequency form of radiation with the longest wavelengths. Many natural objects emit radio waves, from planets to stars, but ...

For more than 50 years, scientists theorized that an electromagnetic wave could be reflected temporally—not just spatially. Scientists have been unable to confirm the existence of time ...

Electromagnetic waves called Alfvén waves transfer energy to electrons, giving the particles an accelerated push toward Earth. Electrons can then surf the waves, ultimately reaching speeds of up ...

In a microwave echo-free chamber, an operator remotely controls metasurface coding sequences through a brainwave module which affects the scattering mode of electromagnetic (EM) waves.
