The film explains the concept of electromagnetic waves, particularly focusing on their applications in radar, radio, and television. It describes how a crystal set functions as a simple radio receiver ...

Abstract: Expressions are given for the diffraction field far behind, and the surface currents on, a parabolic cylinder. Approximate values for the field strength and current density are given when ...

EOMs are commonly used in applications that require q-switching such as research laser systems, military lasers, and medical uses. Their ability to modulate large aperture beams makes them ideal for ...

Abstract: It is shown that a new mode of radio wave diffraction occurs at the peak of mountains mediated via the terrestrial surface plasmon. If mobile electrical charges exist on the Earth's surface, ...

In the years that followed, French engineer August Fresnel’s findings on diffraction ... Using this apparatus, he detected radio waves (which also traveled at the speed of light).

The SKA-Low radio telescope in Western Australia is slowly coming online. It will probe the shape of the universe and study ...

A research team led by McGill identifies neutron stars as the likely source of fast radio bursts, one of the universe's most ...

But de Ruiter didn’t think the star would be able to produce radio waves by itself. Something else had to be instigating it.The pulses differed from fast radio bursts, which are incredibly ...
