Traveling-wave parametric amplifiers (TWPAs) are electronic devices that boost weak microwave signals (i.e., electromagnetic waves with frequencies typically ranging between 1 and 100 GHz). Recently, ...
Physicists at the University of Southampton have tested and proven a 50 year old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by ...
Earlier this year, the James-Webb Space Telescope sent back to Earth some of the most detailed images of other galaxies. This was partly due to a Vacuum Electronics Device (VED) called the Travelling ...
