Abstract

A two-dimensional problem of excitation, by a linear source, of a structure consisting of two identical solid or hollow cylinders made of a metamaterial under the condition that the geometric and material parameters of the cylinders provide for the existence of high-Q quasi-static resonances in each of the cylinders is considered. The effect of the distance between the cylinders on the spatial structure of the resonant fields is studied. It is shown that the frequency response of the structure has the shape characteristic of the response of coupled resonators. The behavior of the fields in the vicinity of the critical coupling, which qualitatively changes the frequency characteristics of the composite resonator, is numerically investigated.
