traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers, MILO)
The book consists of two parts: Part I focuses on the motion of charged particles in static fields, the theory of electron lenses, and the problems of formation and transport of intense electron beams are considered; Part II covers the principles and theory of the interaction of electron beams with electromagnetic waves in quasi-stationary systems (diodes, klystrons), systems with continuous interactions (traveling wave tubes and backward wave oscillators), crossed-field systems (traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers.
Under both the DARPA and ARO contracts Teraphysics will develop a type of vacuum electron device known as a backward wave oscillator.
Citing the unprecedented efficiency and power of Teraphysics' backward wave oscillator designs, the defense agencies are coordinating funding to expedite the introduction of promising technology into the field, according to Dev Palmer, PhD, program manager for electromagnetics and radio frequency circuit integration projects at the ARO office in Research Park Triangle, North Carolina.
65 terahertz prototype producing at least 100 milliwatts within two years, Dayton and his team will develop backward wave
oscillators and traveling wave tubes using the company's proprietary application of nanotechnology for laboratory-grown diamond.
By assuming that the electromagnetic field in the jth medium is a summation of forward and backward waves in the z-direction, the electric field in each layer can be expressed by [6,7]
