grating substrate 中文意思是什麼
grating substrate
解釋
光柵襯底-
To utilize property of saws propagating, it can be made including delay lines, passband filters, oscillators and pitch filters. surface transverse wave ( stw ) was used the configurature of reflective metal - strip grating between the two interdigital transducers, and made the shear horizotal ( sh ) wave on the surface of the piezoelectric substrate, but not to deep in
聲表面橫波（ surfacetransversewave ，簡稱stw ）是採用在兩個金屬叉指換能器之間加入短路柵的隔離板結構使剪切水平波（ shearhorizontalwave ，簡稱sh波）被嵌制在壓電基片表面上，而不是沿壓電基片內傳播的聲表面橫波形式。 -
The arrayed - waveguide grating ( awg ) bases on the planar linear circuit technology of si substrate has two elementary functions : one is multi / demultiplexer, the other is static wavelength router
基於si基片的平面波導迴路技術的陣列波導光柵（ awg ）具有兩個基本的功能：復用解復用功能以及靜態路由功能。 -
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。
