In this webinar, Dr. Husain Shekhani explains why anti-resonance matters in ultrasonic transducers, even for systems operating at resonance. Learn how measuring and simulating anti-resonance can diagnose critical issues, optimize designs, and solve complex problems that might be missed when only examining resonance.
