| Abstract: | Magnetoelectric susceptibility (ξ) of classical
magnetoelectrics is always substantially smaller that the geometric
average of the electric (χ
e
) and magnetic (χ
m
)
susceptibilities. Materials reaching the equality
ξ
2 = χ
e
χ
m
as a limiting value may thus be considered
as ideal magnetoelectrics. Here we investigate the magnetoelectric
susceptibility of a metamaterial built from split ring resonators
both experimentally and within an equivalent circuit model. Due to a
direct proportionality between electric polarization and
magnetization, the magnetoelectric susceptibility of this
metamaterial fulfils the equality ξ
2 = χ
e
χ
m
at least
in the dynamic regime. |
