英文摘要	Characteristics of trapped thickness-twist waves in an inhomogeneous plate consists of the piezomagnetic material and elastic material affected by the magnetic field and compressive stress are investigated theoretically in the article. Variations of the effective elastic, piezomagnetic and magnetic permeability constants in the piezomagnetic material with the magnetic field and compressive stress are analyzed. The active controls of trapping characteristics have been achieved. Bisection method is used to solve the frequency equation of trapped thickness-twist waves. It is found that the number of trapped modes increase as the central region length increase and the magnetic field can not only induce new trapped modes in the structure but also accelerate the energy trapping. The advantage of this method is that the trapping characteristics can be modulated easily and without physical contact. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
