Abstract
The magnetoelectric (ME) effect in a bilayered piezoelectric/piezomagnetic cylinder with an imperfect interface under harmonic excitation is solved analytically. We show that while the interface imperfection would always reduce the static ME effect, the imperfect interface could play a significant positive role in enhancing the ME effect in the frequency domain >100 kHz. Combining with the curvature of the cylinder and the mechanical boundary conditions, we further demonstrate that it is possible to excite large ME effect at double and even multiple resonance frequencies, a unique feature which should be important to various microwave devices, such as antennas.
