Abstract : The objectives of the contract are: to conduct a theoretical and experimental investigation of microwave techniques with a view toward development of devices applicable to surveillance systems. The emphasis shall be primarily directed toward requirements of phased array radar systems. This investigation presently includes the following projects: Thin Film Transducers; Acoustic Parametric Amplification; Domain Fields in Gunn Oscillators; Periodic Ferrite Devices; Adiabatic Magnetoelastic Conversion in the Time Domain; Gunn Effect Theory; and Guided Acoustic Waves. The project titled 'Theory of Carrier Waves Propagation' has been completed and a technical report describing the work has been written: 'Wave Propagation and Instabilities in Semiconductors,' Microwave Laboratory Report No. 1533 (partially supported by an NSF grant). The projects titled 'Electronic Focusing in Acoustic Delay Lines' nd 'Helicon Wave Studies' have been transferred. (Author)
