Voltage tunable magnetoelectric devices

Multiferroic materials have provided more and more opportunities for improving the performance of voltage tunable RF/microwave devices. The coexistence of electric polarization and magnetization in multiferroic materials provides realization of the electric control of magnetism. Strong ME coupling has been the enabling factor for different multiferroic devices, especially at RF/microwave electronics frequencies. In this paper, we will mainly discuss about the basis of voltage tunable RF/microwave devices and multiferroic materials. We will show results of tunable RF devices, such as integrated non-reciprocal tunable bandpass filter with ultra-wideband isolation. These novel magnetics and multiferroic devices show great promise for applications compact, lightweight and power efficient sensing, memory, RF and microwave integrated electronics.
