Simulation of Surface Acoustic Wave Devices [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004 The Mason crossed-field circuit model is generalized to simulate apodized interdigital transducers without channel division. The apodized transducer model is based on the transmission line model, and the artificial transformer with different voltage and current coupling ratios is used to independently obtain the transfer function and radiation ...

Aerothermoelastic-Acoustics Simulation of Flight Vehicles [PDF]
AIAA Journal, 2017 This paper describes a novel computational-fluid-dynamics-based numerical solution procedure for effective simulation of aerothermoacoustics problems with application to aerospace vehicles. A finite element idealization is employed for both fluid and structure domains, which fully accounts for thermal effects.

Acoustic simulation of J.S. Bach’s Thomaskirche in 1723 and 1539
Acta Acustica, 2021 This paper investigates an early acoustical theory of Hope Bagenal about the Leipzig Thomaskirche, where J.S. Bach composed and conducted from 1723 to 1750. Bagenal predicted that the church had a shorter reverberation time than previously in Bach’s time
