EFFECT OF CONCAVE STAVE ON CLASS I BARREL-STAVE FLEXTENSIONAL TRANSDUCER

To meet the requirements of low frequency, high power, small size and light weight, a type of Class I barrel-stave flextensional transducer employing improved concave stave is presented.As the key component of flextensional transducer, concave stave plays an important role in vibrating efficiently to radiate acoustic energy.The structure of concave

Abstract In this paper, we present a proof-of-concept of a new approach to achieving tailored resonant frequency temperature coefficients in dielectric meta-atoms.The technique involves introducing a thermally expanding or contracting material joining the active high permittivity dielectric absorbers.Both simulation BLACK PWD and experiment show th
