N2 - The electromagnetic acoustic transducer (EMAT) can generate non-dispersive T(0,1) mode guided wave in metal pipes for structural health monitoring (SHM). This paper investigates the effect of structural parameters on the properties of the transducer with the goal of enhancing the frequency bandwidth and excitation capability of the transducer. To simulate the torsional guided wave in a carbon steel pipe, a three-dimensional time-domain finite element model is developed. In order to build a broadband torsional guided wave EMAT, the effects of the number of elements, the axial length of the permanent magnet, and the number of axial permanent magnets are explored through simulation. The simulation results are verified by experiments. The results show that the transducer bandwidth and excitation capability can be improved by changing the transducer structural parameters.
