"WebA backward wave oscillator (BWO) is a microwave CW oscillator with an enormous tuning and overall frequency coverage range. It operates on TWT principles of electron beam-RF field interaction, generally using a helix slow-wave structure. In general appearance the BWO looks like a shorter, thicker TWT.

WebA backward wave oscillator ( BWO ), also called carcinotron or backward wave tube, is a vacuum tube that is used to generate microwaves up to the terahertz range. Belonging to the traveling-wave tube family, it is an oscillator with a wide electronic tuning range. An electron gun generates an electron beam that interacts with a slow-wave structure.

WebSep 9, 2024 · The backward-wave coupler is by far the most commonly used, due to its very simple implementation. However, the forward-wave directional coupler (FWDC) presents many advantages such as potentially tight coupling level (ideally 0 dB), high directivity and flexibility in fabrication [ [1] ]. WebIf the coupled signal is traveling in the same direction as the through signal, the coupler is called a “forward-wave” coupler. If in opposition, it is called a “backward-wave” coupler. Because these coupled signals are related to the direction of the through signals, couplers are called directional couplers.

WebSo if I were to really draw this wave, and actually, if this membrane were to keep doing it over, and over, and over again-- so it kept going forward and back, forward and back, or right and left, right and left-- what you would have is a series of compressions. The air would just have a series of compressions. So that's one compression.
