Metamaterial with split ring resonator (SRR) array is proposed to improve the performance for the real-time terahertz (THz)-wave imaging system based on the frequency up-conversion with nonlinear crystal. The SRR works as a micro-antenna to collect the incident THz wave and confine the electric field into the capacitor area at its resonance, where the enhanced electric field reinforces the conversion efficiency on the nonlinear crystal, resulting in improving the detection signals with the image.
