This contract is for Ku and Ka-band high-power travelling wave
tube amplifiers (TWTAs) for a transportable satellite communications ground system.
Thales Alenia Space has signed two contracts with The National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) concerning the delivery of transponders and the travelling wave
tube amplifiers for the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) and Wide Field InfraRed Survey Telescope (WFIRST) missions.
On the basis of product type, the ultrasonic motor market can be segmented into standing wave type and travelling wave
The standard DNLS, arising for [mathematical expression not reproducible], is known to support periodic travelling wave
solutions (see, e.g., ).

Human reaction times can cause a backwards travelling wave
. The first driver to respond to an event on the road brakes, the person behind, due to reaction time, brakes a fraction of a second later and has to brake a little harder to avoid hitting the person in front, the person behind them has to brake harder still, and somewhere down the backward wave the traffic comes to a complete halt.
The travelling wave
thermoacoustic refrigerator (TWTR), designed by a research team at Tokai University, consists of three etched stainless steel mesh regenerators installed within the prime mover loop and one in the refrigerator loop.

Closed and quasi-closed yoke configurations for travelling wave
LUSMs utilizing bending modes of a beam were proposed under direct inspiration of the idea of the disk type travelling wave
