This research aims to widen the bandwidth by means of acoustic beam steering and to find a phase delay that yields high efficiency throughout the working frequency range. The model is based on a geometric basis, which we then compare to experimental measures of efficiency with and without beam steering.5 p.application/pdfengcc-by-nc-nd (c) Tong, 2024http://creativecommons.org/licenses/by-nc-nd/3.0/es/DifraccióDirecció del feixTreballs de fi de grauDiffractionBeam steeringBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
