“…0 and H l0 can also be obtained. Then, we can get P £ and P HE by using the equations,-21 -So, according to (66) and (69) in Section V or (111) and (112), the longitudinal interactions of the plasma waves and the electron beam have been calculated.We find that there are at least two differences between our work and the experiment cited in [28].They are as follows:1) The authors of [28] stated specifically that only "the E-mode" (i.e. -the TM mode) were considered there.…”

“…3. Since the corresponding experimental work has already been published [28], we are able to compare our calculations directly to those results. Since there is only a thin annular plasma background, the ion-channel effect can be neglected and the interaction equations (66) and (69) from above can be used:…”

“…However, theory [19], [20] demands that in an MPW the "E-mode" cannot exist independently. Only the hybrid modes, HE or EH, are allowed.2) It was also indicated in [28] that the modes for which the cut-off frequency is zero and the phase velocity is less than the speed of the light were used.

Progress Report IV Aug. 1999 -Jan. 2000.The Final Report summarizes in its first part the most recent scientific achievements. They are documented in the listed and enclosed copies of publications and drafts of papers. In the second part the recent academic activities are reported, and the third part gives an outlook of planned activities based on the work supported by this grant.I. Publications Prof. Kristiansen of Texas Technical University was invited to visitUESTC and to present several lectures.3. Mr. Bookbander, the officer in charge of literature and education at the United States General Consulate in Chengdu, was invited to visit UESTC and present a lecture. His lecture was very well received and was excellent for the students, both undergraduate and graduate students. III. Preparatory Work on the 25 th Intern. Conference on IRMMWto be held in Beijing, China, Sept. 12-16, 2000. This International Conference will be held jointly with the 2nd Pacific-Asian Conference on Microwave and Millimeter Waves. Prof. Liu is the Conference Chairman for these two conferences. He is in the process of: A. trying to obtain the sponsorship by IEEE. The 2 nd Pacific-Asian Conference is sponsored by IEEE, but the 25 th conference not. B. organizing the committees for both conferences; C. organizing the Plenary Talks and Invited Talks for both conferences; D. preparing the final call for papers for both conferences. IV. Proposed Research Work for the Period from January 2000 to December 20011. Almost all the material published in Russian in the Plasma Microwave Electronics area has been collected. This material is very valuable, since it provides information on what has been done and how it has been done in Russia. From this literature it can be concluded that the work carried on by Prof. Liu and coworkers on the "Electron Beam-Wave Interactions in Magnetized Plasma Waveguide" is very i...

533.922We study the interaction of a rectilinear nonrelativistic electron beam with a solid-state plasma in a rectangular metal waveguide, as well as wave processes in a plasma waveguide of rectangular cross section in the absence of an electron beam. It is shown that in such a system, space-charge waves of an electron beam, which propagate along a semiconductor boundary, become unstable in a wide frequency band. *
