On its 10th anniversary, Third Rock Radio hosts share the history and evolution of the partnership with NASA and bringing space to the airwaves. HWHAP Episode 224.
Waves, signals and other invisible frequencies. In relation to an analysis of the "stettler" posters by Hermann Eidenbenz, these visualization experiments were created. Make the invisible visible!
Distance Measurement With Radio Waves: Introduction: First of all, we want to excuse us for our bad English. (German pupils :D) We invented a new, inexpensive device to measure distances up to 1.5km (about 1 mile) with accuracy about ±5 Meter (15 feet). The use of radio waves makes it po…

Splendid Sampler II – Radio Waves, a Sewing post from the blog Quilting Jetgirl, written by Yvonne Fuchs on Bloglovin’
This experiment shows the transmission of a radio signal between two dipole antennas. It is demonstrated that the distance between the antennas affects the r...
Understanding the basics of radio waves and frequency bands is key to understanding satellite internet technology
Geodesy is the scientific discipline that deals with the measurement of the Earth. One of the measurement techniques it employs uses radio waves from far-distant objects in space to determine factors such as the movement of tectonic plates. A high frequency amplifier promises to boost the performance of the radio telescopes this method requires.
An unknown object in a nearby galaxy is emitting radio waves unlike anything seen before, and it's baffling astronomers
Not quite long, January to be precise, an extremely bright object was sensed to pulse in a totally different way. It is said that this might be a mysterious ...
Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use in detecting ultra-weak magnetic resonance (MRI) signals or for quantum-sensing applications that can help the search for dark matter. The results have been published in Science Advances.
