Picture: military interrogators are talking to a local man they suspect of helping to emplace roadside bombs. The man denies it, even as they show him photos of his purported accomplices. But an ...

Back to our radio signal. The electrons in our wire are moving, but not in one direction. These electrons are moving back and forth. Actually, the wave displayed in the activity is a representation of ...

The basic design of the radio antenna hasn’t changed in a century. The antenna is usually a set of metal rods roughly half the size of the wavelength they are designed to receive. The electric field ...

For the first time, physicists have successfully converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in ...
