“…Two recent papers [25], [26] describe the approximate propagation characteristics and gain performance of some "ring" structures. However, their definition of ring is a biconical body-of-revolution [25] in one case, and a circular arrangement of curved reflectors [26] in the second. A quasistatic version of the axial array of rings appears in the design work of [27] and [28], where artificial magnetic materials are constructed from "split-rings.…”

A boundary value problem is solved for the current induced by any source, in particular for an incident plane wave, on any number of identical rings that are arranged to form an axisymmetric, linear array. The net aperture distribution along the finite array is approximated by a combination of three physically-identifiable components: a term from the related infinite array plus contributions from two independent edge-effect waves that originate from each of the two ends. However, if individually resonant loops are closer than a critical spacing, the entire structure exhibits a wild resonance and the simple approximation becomes invalid.
