If you are rusty on the basic physics of why an antenna radiates, have a look at the very nice animations from [Learn Engineering] below. The video starts with a little history.

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

Researchers from North Carolina State University have discovered a technique for controlling light with electric fields.

Spiders don’t have wings, but they can fly across entire oceans on long strands of silk. For more than a century, scientists thought it was the wind that carried them, but a new study shows the ...

Researchers at Paul Scherrer Institute PSI have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials ...

Flowers generate weak electric fields, and a new study shows that bumblebees can actually sense those electric fields using the tiny hairs on their fuzzy little bodies. "The bumblebees can feel ...

Controlling light with electric fields is difficult. Photons, the basic units of light, are neutral -- they have no charge, so they usually do not respond to electric fields.
