Think of RIS like mirrors. They are thin surfaces that can redirect the propagation direction of radio waves. Instead of bouncing around randomly, radio waves can be purposefully directed in a way ...

Radio wave propagation underpins numerous applications in communication, surveillance and remote sensing, and understanding its nuances is essential for the advancement of modern wireless ...

Model of extending radio wave coverage using reconfigurable intelligent surfaces Date: July 11, 2024 Source: Tohoku University Summary: Researchers developed a model showing the ability of ...

Researchers at Tohoku University and the UK developed a model showing the ability of reconfigurable intelligent surfaces to redirect the propagation of radio waves, which could improve the signal.

The Kent Amateur Radio Society team meets outside President Chris Cote's bus configured to receive satellite communications.

The ANITA experiment, built to detect neutrinos, has detected very strange radio waves coming from deep below the Antarctic ice.

When flares ionize the Earth's ionosphere, they interfere with radio wave propagation, particularly for frequencies below 30 ...

Physicists can’t explain mysterious radio wave emissions in Antarctica The anomalous readings ‘appear inconsistent with the standard model of particle physics.’ By Andrew Paul ...

The Indiana County Amateur Radio Club hosted its annual Amateur Radio Field Day program Saturday at Blue Spruce Park.

When flares ionize the Earth's ionosphere, they interfere with radio wave propagation, particularly for frequencies below 30 MHz, resulting in shortwave blackouts.

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect ...
