backward wave oscillator वाक्य

उदाहरण वाक्य

1. Coupled mode theory first arose in the 1950s in the works of Miller on microwave transmission lines, Pierce on electron beams, and Gould on backward wave oscillators.
2. :While this is possibly theoretically possible, this is still around 600 times higher frequency than can be generated through devices such as a Backward wave oscillator, which produce Terahertz radiation.
3. In addition, producing and detecting coherent terahertz radiation remains technically challenging, though inexpensive commercial sources now exist in the 0.3 1.0 THz range ( the lower part of the spectrum ), including gyrotrons, backward wave oscillators, and resonant-tunneling diodes.
