The thesis is a presentation of published work with a commentary. The 25 publications cover the period from 1961 to 1974, and with one exception (on the subject of silicon transistor circuits) are in the general area of microwave electronics.Work on tunnel diode amplifiers includes a stability criterion, a measurement technique, amplifier designs for U.H.F. and X-band frequencies, and application to short hop radio-relay systems, General purpose computer programs for the analysis of microwave circuits are discussed. The method of using chain matrices, which has since found 0ide application, is presented.Work on microwave integrated circuits is presented which is mainly concerned which measurement techniques, and material and component properties. Measurement techniques are presented for thin dielectric films, rectangular dielectric plates, thin conducting metal films, and overlay capacitors. In each case microwave properties not previously obtained, are presented.
