Abstract
A resonator comprising a magnetoelastic body having a mass load portion and an active resonating portion can be used in implementations such as a security tag. The resonator includes a mass at the mass load portion of the magnetoelastic body. Displacement of the magnetoelastic body is configured to occur at both the mass load portion and the active resonating portion. A strain at the active resonating portion during displacement is configured to be greater than a strain at the mass load portion during displacement.
