Simulated (A) and measured (B) transmission coefficient on dB scale, 10log10(T), of a single-layer triple-negative metamaterial (MM), indefinite MM, and freespace for coil-to-coil distances of 8 cm (blue curves), 16 cm (green curves), and 24 cm (red curves). Simulated (C) and measured (D) 10log10(T) of a 3-layer MM and freespace for the same distances.
