Nettet15. mar. 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) … NettetRecall that the linear wave equation is ∂ 2 y ( x, t) ∂ x 2 = 1 v 2 ∂ 2 y ( x, t) ∂ t 2. Therefore, 1 v 2 = μ F T. Solving for v, we see that the speed of the wave on a string depends on the tension and the linear density.
