UP to the present date, short electromagnetic waves have been generated only by the method of the Hertz vibrator. This method offers very serious difficulties when we try to produce ...

When British physicist Roger Penrose suggested in 1969 that energy could be pulled from a rotating black hole, it sparked a half-century of exploration. Penrose proposed that inside the ergosphere—the ...

Trying to get Wi-Fi to reach all areas in your home? There's some nuance to getting the most out of your Wi-Fi connection.

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter.

All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...
