unusual facts about electromagnetic waves



Charles F. Brush

Between 1910 and 1929 he wrote several papers on his version of a kinetic theory of gravitation, based on some sort of electromagnetic waves.

Jerry Goldstein

Goldstein got his B.S. at Brooklyn College and his Ph.D at Dartmouth College, where he studied magnetospheric cavity mode resonance, a phenomenon in which the Earth's magnetic field traps electromagnetic waves.

Time reversal signal processing

Some media are not reciprocal (e.g. very lossy or noisy media), but many very useful ones are approximately so, including sound waves in water or air, ultrasonic waves in human bodies, and electromagnetic waves in free space.

Bessel function

This differential equation, and the Riccati–Bessel solutions, arises in the problem of scattering of electromagnetic waves by a sphere, known as Mie scattering after the first published solution by Mie (1908).

Evanescent

Evanescent wave, a term applied to electromagnetic waves that decay exponentially

Induction coil

They were used by Hertz to demonstrate the existence of electromagnetic waves, as predicted by James Maxwell and by Lodge and Marconi in the first research into radio waves.

Narayanan Komerath

In May 2003 Popular Mechanics reported that Komerath had found a way to crush the rocks in the asteroid belts using electromagnetic waves and assemble them into radiation shields and structures where humans could live, among other purposes.

Varian Medical Systems

Varian was founded in 1948 as Varian Associates by Russell H. Varian, Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the Klystron, the first tube which could generate electromagnetic waves at microwave frequencies, and other electromagnetic equipment.
