Abstract: A magneto-electric (ME) gyrator, which is a discrete, passive network element, comprises a laminated composite of piezoelectric and magnetostrictive layers. The ME gyrator approximately meets the following criteria: Vy=??/,, where V is voltage, /is current, and a is a conversion (or gyration) coefficient between voltage and current and non-reciprocity is manifested as a 180° phase shift between open and short circuit (/,F) conditions, and =* 1 (Ib) where c0 is the speed of light in vacuum, ?e?is the effective relative dielectric constant, and ?c?is the effect?ive relative permeability.
