This　paper　presents　a　method　which　combines　electromagnetic　simulation　and　ultrasonic　simulation　to　build　EMAT　array　models.　For　a　specific　sensor　configuration,　Lorentz　forces　are　calculated　using　the　finite　element　method　(FEM),　which　then　can　feed　through　to　ultrasonic　simulations.　The　propagation　of　ultrasound　waves　is　numerically　simulated　using　finite-difference　time-domain　(FDTD)　method　to　describe　their　propagation　within　homogenous　medium　and　their　scattering　phenomenon　by　cracks.　Radiation　pattern　obtained　with　Hilbert　transform　on　time　domain　waveforms　is　proposed　to　characterise　the　sensor　in　terms　of　its　beam　directivity　and　field　distribution　along　the　steering　angle.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
