Abstract :
We show that a semi-infinite magnetoelectric (ME) material adjoining a vacuum sustains the propagation of a shear horizontal wave accompanied by electromagnetic waves. The ME material is assumed to possess hexagonal (6 mm) symmetry. The expression for the phase velocity of this wave is obtained explicitly. The result is helpful for applications of piezoelectric-piezomagnetic composites to acoustic wave and microwave devices.
