There are all sorts of resonances around us, in the world, in our culture, and in our technology. A tidal resonance causes the 55 foot tides in the Bay of Fundy. Mechanical and acoustical resonances and their control are at the center of practically every musical instrument that ever existed. Even our voices and speech are based on controlling the resonances in our throat and mouth. Technology is also a heavy user of resonance. All clocks, radios, televisions, and gps navigating systems use electronic resonators at their very core. Doctors use magnetic resonance imaging or MRI to sense the resonances in atomic nuclei to map the insides of their patients. In spite of the great diversity of resonators, they all share many common properties. In this blog, we will delve into their various aspects. It is hoped that this will serve both the students and professionals who would like to understand more about resonators. I hope all will enjoy the animations.

The Author

The author is a retired professor of both physics and electrical engineering. After receiving his Ph.D. from Stanford in physics, he taught electromagnetic fields and elementary labs at George Mason University, in Fairfax, Virginia for 30 years. He was one of the originators of thermoacoustics (engines and refrigerators using acoustics instead of pistons) and has done research in superconducting microwave resonators, electron beam microwave amplifiers, worked with a startup company Microwave Technology, Inc, and worked on the roots of quantum mechanics. He has long felt that computer animation could aid in the teaching of waves and fields.

If you google on Ceperley you may notice the great volume of hits on D.M. Ceperley, a brother, who is also a physicist and is at the University of Illinois.
