Experience

• 

  University at Buffalo

  • Consultant/Professor Emeritus

    • 1992 - Present

    I have participated in the design or improvement of transmitters for a large number of military microwave systems. I was instrumental in the establishment of a NASA/USAF program to develop high efficiency TWTs for electronic counter measures systems. I have worked extensively with Government personnel to correct deficient tube and system designs in order to reduce failure rates and enhance performance.I have presented over 100 courses on microwave tubes to over 2000 scientists, engineers, managers and technicians. These include in-depth courses eight to ten days long (two days/month for several months) three time each at each of the major US manufacturers of microwave tubes.I compiled and published the Conference Records of the Power Modulator Symposia (over 5000 pages), and wrote and published books "Microwave Tubes," "Principles of Traveling Wave Tubes," "Klystrons, Traveling Wave Tubes, Magnetrons, Crossed-Field Amplifiers and Gyrotrons," and "Principles of Traveling Wave tubes (with major revisions, March, 2014)."
