Description: Topic: Transducers for Acoustic Helicoidal Beams
Location: College of Engineering Conference Room, Textiles Building (TXT), Room 101E
Abstract:
A piezoceramic transducer using two orthogonal dipoles driven in phase quadrature to create an acoustic helicoidal Bessel beam (HBB) with constant amplitude and phase varying linearly with azimuthal angle. The HBB has the capability of causing axial forces (torque) on the object that the beam is reflecting from. A disc and sphere were used to create two proof of principle units along with experimental results including directional factors, and computed receive phase vs. bearing angle.
NOTE: All ECE Graduate Students are ENCOURAGED to attend.
All interested parties are invited to attend. Open to the public.
Advisor: Dr. David A. Brown
Committee Members: Dr. Paul J. Gendron and Dr. Dayalan P. Kasilingam, Department of Electrical & Computer Engineering and Dr. Corey Bachand, BTech Acoustics, LLC
