▲ [14a-211-6] Terahertz Generation from Split Ring Resonator Array Fabricated from Silver Nano-Particles
キーワード：terahertz generation, silver nano particle, split ring resonator
The study of terahertz (THz) wave is bringing back many developments in science and application. Previous reports show that terahertz emission from metal surfaces irradiated with ultra-short laser pulses is improved significantly by plasmon resonance on nano-structures. In this report, we propose a split ring resonator (SRR) array fabricated by silver nano particles, which exhibits both resonances for generated terahertz wave and incident laser light, respectively. This structure is expected to enhance the nonlinear process converting the laser pulse into the THz pulses.
