Book excerpt: Progress on ultrasonic delay line research is discussed. The results of a continued study of lead as a bonding and backing material for ultrasonic delay lines are presented. The tripletravel response level was reduced below the level of spurious responses due to diffraction for a majority of delay line applications. The results of an investigation of the diffraction field, in a solid medium, of an ultrasonic transducer are presented. The experimental results indicated that the assumptions made in the mathematical description of acoustic diffraction phenomena are valid. Design techniques for polygonal delay lines are discussed in terms of spurious response levels. A theoretical analysis, based on Fresnel diffraction theory, is presented, which results in the determination of the optimum transducer length for minimum spurious response level. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The report presents the theory, design and performance of microwave ultrasonic delay lines, and the results of investigations of related ultrasonic topics. The design considerations include specification and processing of delay materials, development of microwave ultrasonic thin-film transducers, studies of acoustic wave propagation, development of microwave networks for coupling to ultrasonic transducers, and design of delay line packages. Investigations are also reported of spurious suppression means and of power capability for ultrasonic delay lines. Prototype microwave ultrasonic delay lines were developed and delivered to specifications in the 500 to 2000 MHz frequency range with less than 36 db insertion loss over nominal 10 percent bandwidth, delay values from 0.3 to 3 microseconds, greater than 1 milliwatt output power, and spurious signals at least 20 db below the desired signal. The delay line packages are of shielded stripline construction, with a nominal volume of 1 cubic inch and weight of 6 ounces, suitable for operation over a large range of environmental conditions. Data on 12 delivered delay devices are reported, together with conclusions on the performance capabilities and limitations of microwave ultrasonic delay lines. (Author).

Book excerpt: Results are presented of a continued program on delay line development. Work concerned the two major areas of dispersive ultrasonic delay lines, and of thin ferroelectric ceramic sheet lines. Ceramic sheet lines were studied theoretically and experimentally, and a number of novel configurations are presented. Ceramic sheet lines offer the possibility of building ultrasonic delay lines with relatively small time delay - bandwidth products having large numbers of taps. Tap spacing can be made less than the resolution time, and transducer reflections are minimal because transducers and delay path utilize the same material, with the same acoustic impedance and with no intermediate bonds. Time bandwidth product is limited at present by attenuation in ferroelectric ceramic materials suited to this application. One application is described, which provides an ultrasonic means for scanning an image area to provide a raster suitable for television cameras or image display. Dispersive delay line development continued from a previous RADC program. Bandwidths and operating frequencies were increased substantially, strip configurations were developed, and practical lines suitable for pulse compression systems were built, both in breadboard form and in finished packages suitable for system use. The results of operation in a laboratory pulse compression system are presented. (Author).
