The dynamic focused ultrasound radiation force has been recently used for excitation of structures with sizes ranging from micro to macro scale having a frequency bandwidth between tens of Hertz and up to 100 kHz. Therefore it can potentially be used as an alternative non-contact excitation method for conventional contact type excitations such as modal impact hammer or shaker excitations for experimental modal analysis. However, the dynamic focused ultrasound radiation force remains to be quantified and calibrated. In this paper, we present the results of numerically modeling and experimentally mapping the pressure field generated by a focused ultrasonic transducer (UT) with a radiating diameter of 50 mm and center frequency of 359 kHz. In the simulation, an acoustic model is created using the Rayleigh Integral and the boundary element method. For the experimental testing, a precision microphone and a fiber optic acoustic sensor are used to map the pressure field generated from the UT driven by double sid...
