It is known that in the space surrounding the Earth (the space up to the geostationary orbit altitude, called Geospace), there are natural trapped charged particles, Van Allen belts, that may affect ...

Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible ...

There are seven types of electromagnetic (EM) waves, which make up the electromagnetic spectrum. Electromagnetic waves are transverse waves, and travel at the speed of light. Different types of ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...

Electromagnetic waves are packets of energy travelling all around us. Some of these waves have lots of energy, and some have less. We call the lowest energy electromagnetic waves radio waves. There’s ...
