Back to our radio signal. The electrons in our wire are moving, but not in one direction. These electrons are moving back and forth. Actually, the wave displayed in the activity is a ...

The first steps toward inventing radio involved discovering electromagnetic waves and their potential ... that by sending the first long-distance transmission of human voice and music from ...

A new patterned spintronic emitter enables room-temperature control of terahertz wave polarization.

AMONG the facts to be explained in a satisfactory theory of the propagation of radio waves over the earth's surface are the curvature of the rays in transmission between stations far apart ...

Sending electromagnetic waves into the air. In 1894, Marconi transmitted the first radio waves. The first commercial radio station to transmit audio frequencies was KDKA in Pittsburgh ...

Like most waves in the electromagnetic spectrum, radio waves tend to bounce off of various objects. This can be frustrating to anyone trying to use something like a GMRS or LoRa radio in a dense ...

In August 1977, a strange transmission was picked up during a routine scan for signals of alien life. For more than one ...

A Ham radio operator will tell you all about ... All well and good, but what do standing waves actually look like in a transmission line? [Allen] obliges with a demo using a strip line, which ...

JDI’s LC Meta-Surface reflector technology applies JDI’s world-leading expertise in liquid crystals to optimize and significantly improve 5G radio wave transmissions. By reflecting and ...
