Vacuum microelectronics becomes one of the most important directions in the development of microwave electronics used in radar complexes, telecommunication devices and information processing systems .
Therefore, we can say that vacuum microelectronics and vacuum nanoelectronics allow creating fundamentally new microwave vacuum lamps, as well as essentially new and highly efficient flat cathodoluminescent displays .
By focusing on wideband RF amplifiers, DARPA is anticipating EW applications for RF vacuum microelectronics.
Vacuum microelectronics combines the potential of solid-state micro-fabrication techniques with the power handling capabilities of electron transport in vacuum.
The vacuum electronics branch's technical areas of activity include generation and amplification of high power sources for coherent electromagnetic radiation from Ultra-High Frequency (UHF) to terahertz (THz), high brightness electron-beam optics, surface science related to electron emission mechanisms, development of new types of microwave absorbing composite materials, vacuum microelectronics
, development and application of the nonlinear theory of the beam-wave interaction and advanced computational physics for the modeling and simulation of vacuum electronic devices.
These areas are the microwave power module, computer-aided design, high performance mm-wave devices, design for low cost, and vacuum microelectronics
and a supporting technology.
