Electromagnetic pulses (EMPs)—high-energy-density and ultra-wideband beams of electromagnetic radiation—are generated from sources such as nuclear explosions, high-power electromagnetic pulse devices, ...

Nearly 20 years ago, researchers at Oregon State University began leading an effort to collect information about the structure and evolution of the North American continent using electromagnetic ...

Imagine, right now, as you read these words, you're immersed in an unseen ocean of energy. Waves are zipping through your ...

Cassini mission data shows Saturn’s moon Enceladus generates Alfvén waves extending over 504,000 km, circulating energy and momentum through Saturn’s magnetosphere, according to Universe Today and ...

Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers ...

Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror image ...

What is Electromagnetic Radiation? When you sit in front of a computer or television, you are being bombarded by harmful waves quietly emanating from it. Even if you turn off the device, your ...

Electromagnetic fields are all around us — power lines and household appliances produce extremely low frequency EMFs, whereas cell phones and Wi-Fi devices emit radiofrequency EMFs. The general ...

Public and political concerns over potential adverse health effects of environmental electromagnetic radiation exposure have grown in proportion to the use of the mobile digital technology that drives ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...
