“…Lim and Shoureshi [28] presented an approach to detect a broken conductor's strands by analyzing the reflected displacement waves using Electromagnetic Acoustic Transducer (EMAT) in the year 2006. EMAT measured the waves generated by a conductor's vibration which required an additional monitoring device to be installed on each towers and conductors.…”

Electromagnetic acoustic transducers (EMATs) are widely used in industries due to its non-contact nature. This paper investigates the beam features of unidirectional Rayleigh waves EMATs, especially the effect of the wire length on beam directivity. A wholly analytical model is developed to calculate the Lorentz force distribution and ultrasound displacement distribution. The modelling results indicate that, compared to the coil consists of shorter wires, the coil consists of longer wires results in a narrower bandwidth of main lobe of unidirectional Rayleigh waves, which means the ultrasound are more concentrated. This study can be used for unidirectional Rayleigh waves EMATs design and optimization.
