Advanced computer modeling of magnetomechanical transducers and their sound fields

An advanced numerical calculation scheme based on finite and boundary elements as well as multigrid methods is presented. This scheme is used for the precise forecast of the dynamical behavior of magnetomechanical devices, especially sensors and actuators. Application examples include solenoid valves, electromagnetic sources for the generation of acoustic shock waves, magnetic surface acoustic wave (SAW) filters, electrodynamic loudspeakers and electromagnetic acoustic transducers (EMATs).
