Аннотация

A flat resonator having properties of an artificial magnetic conductor is analyzed. Frequency dependences of the radar cross sections (RCSs) of such resonators are calculated and measured at microwave frequencies. Surface impedances |Z| of resonators with different thicknesses are calculated numerically. It is demonstrated that the maxima of local RCSs and impedance averaged over the surface |Z|av are shifted towards lower frequencies as the resonator thickness increases. It is found that the maximum values of |Z|av reach 3000 Ω, which many times greater than the value of the free�space impedance 120Pi Ω. The frequency band in which |Z|av > 1000 Ω is wider than 200 MHz.
