How Nikola Tesla’s AC and radio waves could unlock wireless electric vehicle charging

Electric vehicles are becoming increasingly popular, but range anxiety and charging time are obstacles to their widespread acceptance. Imagine, however, charging your car by simply changing lanes and heading to special charging strips built into the road. This is exactly the vision of Khurram Afridi, associate professor of electrical and computer engineering at Cornell University. […]

Famous FRB radio waves surprisingly long and late | Space

In this illustration, a burst of radio emission from a repeating fast radio burst arrives at the LOFAR telescope. The longest part of the signal (red) is much longer than ever before from a fast radio burst. Also, the longer wavelength emission arrives about 3 days later than the shorter wavelength (higher frequency, shown in […]

Mysterious fast radio bursts include lower frequency radio waves than previously detected

A burst from the periodically active repeating fast radio burst source 20180916B arrives at the LOFAR telescope. High frequency radio waves (purple) arrive earlier than low frequency radio waves (red). The inset shows an optical image of the host galaxy of the fast radio burst source and the position of the source within the host […]

The space bubble created by radio communication signals protects against radiation

We’ve already managed to mess up Earth with everything from overfishing landfills to nuclear fallout, so it shouldn’t come as a shock that human activity is finally manifesting itself in space. The unexpected of our influence beyond the atmosphere is that it is (for once) positive. Something weird had pushed further and further away the […]

What are radio waves? | Live Science

Radio waves are a type of electromagnetic radiation best known for its use in communication technologies, such as television, cell phones, and radios. These devices receive radio waves and convert them into mechanical vibrations in the speaker to create sound waves. The radio frequency spectrum is a relatively small part of the electromagnetic (EM) spectrum. […]
