This FAQ provides a technical overview of harmonics, their primary sources, and the industry standards established for their control.

New research shows that the brain’s ability to detect subtle visual changes—like spotting an anomaly on a security monitor—depends on theta-frequency brain waves (3–6 Hz) that rhythmically sweep ...

Abstract: Vortex electromagnetic waves (VEMW) have unique wavefront phase modulation characteristics. As a new freedom of degree in diversity for radar transmitter, the VEMW radar (VEMWR) can yield ...
