Abstract
Single-resonance models of the constitutive parameters of artificial isotropic chiral composites are analysed. Limitations
on the medium parameters which follow from non-negativeness of the field energy density are established and discussed. The
analysis is restricted to the frequency regions where the losses can be neglected. As a results, it is shown that the single-resonance
model cannot be used at frequencies far from the resonance or the low-frequency region.
