摘要
为了探索对顶四面锥尖在分子损伤和检测中的应用,利用处理色散介质的时域有限差分法((FD)2TD)计算和分析了对顶四面锥尖之间的光增强,研究了不同锥体长度和激励光波长对光增强的影响.模拟表明:在相同平面激励光波长下,光增强效果随锥体长度而改变,且在一定长度范围内有最佳值;在相同的对顶四面锥结构下,长波长平面激励光波引起的光增强较大.这些性质的得出,可以为对顶四面锥尖在生物学中的应用提供理论依据.
In order to understand the application of opposite vertical pyramidal tips in single molecule damnification and measuring system, enhancement of opposite vertical pyramidal tips was analyzed and computed. Also, influence of different pyramidal tip lengths and excitation light wave lengths on light enhancement was studied. It shows that with the excitation of same wave lengths, light enhancement varies with pyramidal tip lengths and optimized value of light enhancement is obtained. Furthermore, with the same diagram of opposite vertical pyramidal tips, light enhancement is larger with the excitation of longer wave lengths. All these properties obtained above can provide foundation on the application of opposite vertical pyramidal tips in biology science.
