Trapped-Mode Resonance Regime of Thin Microwave Electromagnetic Arrays with Two Concentric Rings in Unit Cell

Figure 3

Current distribution on the rings for y-polarized normally incident plane wave. In (a), the normalized current distributions on the two rings are shown, and in (b) the absolute values of current density on one half of the outer ring at trapped resonance and at usual resonance are presented.
