entrance slit

Results indicate that the surface plasmon resonance peak value keeps unchanged and the localized waveguide resonance peak red-shifts and falls obviously when the entrance slit width narrows . However when the entrance slit becomes extremely small the surface plasmon resonance peak red-shifts and falls sharply .

结果表明：当入口狭缝变窄时，表面等离子体共振峰基本保持不变，而局域波导共振峰明显红移且峰值下降，但是当狭缝变的非常狭窄时，表面等离子体共振峰剧烈的红移且峰值下降。
