Vacuum Electronics For 21st Century

[aruljothi]

Vacuum electronics technology is both old and new. It will continue to be enabling technology for entire classes of high power high frequency amplifiers with the most demanding specification for use in military and commercial systems. The report will give brief introduction on various vacuum electronic amplifiers such as helix TWT, gyro amplifiers, multiple beam-amplifiers, power modules along the basics and the advance in the past few decades with different performance curves.

The advantages and the future of these are mentioned in last pages of the report. Vacuum electronic amplifiers are playing, and will continue to play, a major role in emerging market and the whole world needs. In the decades to come, further physics-based high-fidelity simulation software will offer the capability to solve the design problems involving intricate 3-Dnon-symmetric structures incorporating advanced emitters and materials.

Modern numerical techniques and advanced algorithms will provide the foundation for physics based models to conduct trade-of analysis required to optimize amplifiers for specified design goals. This computer aided design capabilities will be used to exploit the full potential of existing amplifier performance.


          Vacuum electronics will continue to produce revolutionary advances, as it has done for decades.  but the existing possibilities opened up by new design tools, new approaches, and new electromagnetic structures , can be counted on to yield a continuing stream of revolutionary advances in RF amplification..
