摘要

An electrostatically tunable magnetoelectric inductor including: a substrate; a piezoelectric layer; and a magnetoelectric structure comprising a first electrically conductive layer, a magnetic film layer, a second electrically conductive layer, and recesses formed so as to create at least one electrically conductive coil around the magnetic film layer; with a portion of the substrate removed so as to enhance deformation of the piezoelectric layer. Also disclosed is a method of making the same. This inductor displays a tunable inductance range of 5:1 while consuming less than 0.5 mJ of power in the process of tuning, does not require continual current to maintain tuning, and does not require complex mechanical components such as actuators or switches.
