We have recently succeeded in detecting the diffraction pattern of radio waves scattered from the electron trail as a meteor passes at right angles through the aerial beam. These observations lead ...

Abstract: The diffraction of electromagnetic waves by a dominating tree-covered ridge north of Ottawa has been the subject of an experimental investigation. The measurements were made at 173, 493, and ...

RADAR stands for RAdio Detecting And Ranging and as indicated by the name, it is based on the use of radio waves. Radars send out electromagnetic waves similar to wireless computer networks and mobile ...

The U.S. military has trialled at least two weapons systems designed to take down drone swarms, but both use microwave energy rather than radio waves. In 2023, the U.S. Air Force Research ...

Definition: Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from the astronomical object was created in the 1930s ...

A UK startup wants to build a cosmic radio station in the Moon’s orbit to listen to radio waves from the early universe. Blue Skies Space has secured a contract from the Italian Space Agency ...

A pulsar is a neutron star, a super-dense stellar remnant that produces beams of radio waves and an energetic "wind" of particles. The pulsar and its wind move with supersonic speed through the ...
