Radiation from charged moving periodic fiber

Radiation from charged moving periodic fiber is investigated. The analysis shows that the source is represented by summation of time-and-space harmonics, which in turn can arouse electromagnetic radiation under rather loose conditions. The amplitude of radiation is proportional to the speed and frequency shift depends on the speed and the period of the fiber. The explored physical effect can form the foundation of macroscopic motion detection and speed measurement and have significance in interdisciplinary fields.
