Scattering-Matrix Description and Near-Field Measurements of Electroacoustic

Évaluation du vendeur 5 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book presents a comprehensive theoretical framework for the measurement of electroacoustic transducers in fluids. It translates and adapts analytical techniques developed for microwave antennas at reduced distances to the measurement of electroacoustic transducers. The theory is formulated in scattering-matrix form, emphasizing the use of plane wave spectra for the representation of sound fields, providing a suitable approach for solving problems involving interactions at arbitrary distances. One novel technique utilizes deconvolution of planar scanning data, taken with a known transducer at distances much less than the Rayleigh distance. This provides a means of obtaining complete effective directivity functions, corrected for the effects of the measuring transducer. The applicability of a (two-dimensional, spatial) sampling theorem and the fast Fourier transform algorithm, which greatly facilitate the necessary computations, is also demonstrated. Another technique extrapolates the received signal as a function of distance and provides a means of obtaining on-axis values of effective directivity observed at distances less than the Rayleigh distance. This book rigorously utilizes observed output of non-ideal (but linear) measuring transducers, making it a valuable resource for researchers and practitioners in the field of electroacoustics. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781527924987_0
