Abstract
This paper presents an approximate, but simple, theoretical model for computing the constitutive parameters of artificial chiral materials made by embedding small conducting helices in a lossy isotropic achiral host material. The model explicitly includes helix resonance and the first-order effects of reradiation from the helix, near-field losses, and mutual coupling. Computations made using the model are compared with published data and qualitative agreement is obtained.Keywords
