A passive isolator realized by magnetoelectric laminate composites

Abstract

This work demonstrates a passive isolator realized by magnetoelectric laminate composites. The proposed isolator consists of a magnetoelectric gyrator, two impedance matching networks, and a load impedance. The equivalent circuit model of the isolator is developed. Good agreement has been obtained between the measured and computed results based on the proposed equivalent circuit model. The measured forward insertion loss and reverse isolation of the proposed isolator are 4.7 dB and 19 dB, respectively. A figure-of-merit which determines the performance of the isolator is proposed, which can be used to guide the design of such isolators.
