reflectance grating 中文意思是什麼

reflectance grating 解釋
反射光柵
  • reflectance : n. 【物理學】反射比；反射能力[系數]。
  • grating : n. 1. 格柵，格子；（船上作地板或透光用的）格子板，格子蓋。2. 【物理學】光柵。adj. 刺耳的，使人煩躁的，討厭的。n. 摩擦，摩擦聲。adv. -ly
  1. I also carried some research on the bragg grating composed by alternate left - handed material and right - handed material. in the reflective spectrum of the bragg grating, there exists bragg top zone ( with reflectance almost 100 % ). however, i found that there exists some narrow transmission bands located in the bragg zone under some conditions

    另外，這篇論文里還要講到正負交替的材料組成的布拉格光柵也有很反常的現象，在光柵的反射譜上，我們不僅可以觀察到和傳統布拉格光柵相類似的布拉格平頂區，我們還可以看到在一定條件下，布拉格平頂區中會有一個很窄的反常透射區，也就是說只有很窄區域的波長可以透過光柵，而且中心波長是100 %透過。
  2. By computer simulation and calculation, the relation between the reflectivity and the structure parameters of such gratings are presented. these results show that a glass grating can achieve antireflection over almost the whole visible light waveband for unpolarized light, while a silicon grating with a columned grid substrate also can achieve low reflectance over as a broad field of view as a tapered silicon grating structure can, but it can be fabricated more simply

    理論分析發現硅基底的圓柱形網格光柵能夠在比較大的視場獲得比較低的反射率，具有特定參數結構的低反射率硅基底圓柱形網格光柵可以獲得與專為大視場設計的金字塔形網格光柵相同的視場角，但它的製作更容易，更簡單。
