This Article contains errors in Figure 6: the axes are incorrectly labelled. The correct Figure 6 appears below as Figure 1. As a result, the Figure Legend,

Dependence of resonance wavelength on the length of l2 and l3 (l2 = l3). The red dots indicate the simulated resonance positions of mode 1 and mode 2, and the black rectangles represent the calculated resonance positions of mode 2 based on LC equivalent circuit model. When the l2 changes, the l3 varies simultaneously with l2, and they always remain the same length (i.e. l2 = l3).

“Dependence of resonance wavelength on the length l2 and l3. The red dots indicate the simulated resonant mode 1 and mode 2, the black rectangles represent the calculated resonance.”

should read:

“Dependence of resonance wavelength on the length of l2 and l3 (l2 = l3). The red dots indicate the simulated resonance positions of mode 1 and mode 2, and the black rectangles represent the calculated resonance positions of mode 2 based on LC equivalent circuit model. When the l2 changes, the l3 varies simultaneously with l2, and they always remain the same length (i.e. l2 = l3).”
