Abstract
A simulation has been carried out and the effects of the operating frequency and the design features of an antiphased electromagnetic-acoustic transducer on its directivity characteristics, as determined by the angle of incidence and the width of the main lobe, the amplitude of the side lobes, and the appearance of additional lobes, have been studied.
