In order to reach the terahertz regime this speed needs to be pushed a thousand times further to a trillion times a second. Terahertz (THz) technology refers to the use of electromagnetic waves in the ...

When introducing the concept of a spaser, it is first useful to explain how it is possible to beat the diffraction limit and focus electromagnetic waves to spots much smaller than a wavelength.

Electromagnetic waves travel at 300,000,000 metres per second (m/s) through a vacuum. Often a phrase is used to help remember the order of the groups of the electromagnetic spectrum such as Roman ...

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 ...

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 ...

THz waves, located in the far-infrared region of the electromagnetic spectrum, can be used to perform non-invasive imaging through opaque materials for security and quality control applications.

There’s tons of theory out there to explain the behavior of electronic circuits and electromagnetic waves. When it comes to visualization though, most of us have had to make do with our lecturer ...
