Periodic Shear Horizontal (SH) wave EMATs (SHG1031-S/SHD1031-S) designed for Pitch-Catch with broadband drivers (e.g. Low Frequency Pulser, available on request) or using a toneburst system.
These EMATs generate a shear horizontal wave either as a plate mode in a thin sheet, or a bulk wave in thicker material with the angle of propagation dependent on the driving frequency. This allows it to be used in a range of novel applications, such as frequency controlled scanning.
(UPDATE): Miniature and broadband SH EMATs, as developed by our research partner organisation the University of Warwick, are now available - please enquire for details!
