Unlike submillimeter waves, infrared light spans a vast range of the electromagnetic spectrum from 0.04 inches (just below 1 millimeter) on the side bordering with microwaves to 0.75 micrometers ...

New research on the last, hidden part of the electromagnetic spectrum is producing new, safe and non-destructive tests for medicine, security and industrial quality control.

Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless ...

For simplicity, let's consider one of the waves describing either the electric or magnetic field displayed in Figure 3.1. This wave can be considered as a component of the more complex electromagnetic ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

Where the information comes from: In the experimental part of the work, the researchers placed Teflon objects (orange cylinders) in a waveguide with a rectangular cross-section. They then injected an ...

Michael Faraday, a brilliant English scientist, was part of this effort, and in 1821 put it to work to invent EM rotation, the principle behind the electric motor.
