Abstract

Highlights: [•] We develop a spatial transversal filter model for meander-line coil EMATs. [•] The generated wavelengths have to belong to the wavelength spectrum of the EMAT. [•] The characteristics of multiple wavelengths will cause the multi-modes phenomenon. [•] Developing a new meander-line coil with special geometric pattern. [•] Proposing a method for removing the effect of multiple wavelengths. [Copyright &y& Elsevier]
