angular spectrum

基本解釋

The angular spectrum method of plane electromagnetic wave propagation gives another explanation for wave propagation.
平面電磁波傳播的角譜法，提供了波的傳播過程的另一種解釋。
The theory of the angular spectrum and the uncertainty relation in quantum theory are applied to discuss the ultra-highresolution beyond Rayleigh diffraction limit.
利用角譜衍射理論和量子力學(xué)不確定關(guān)系對(duì)于掃描近場(chǎng)光學(xué)顯微鏡的基本原理——超衍射極限分辨率的突破進(jìn)行了定性分析。
According to vector diffraction theory, the optical field incident on a facet of a solid immersion lens(SIL) is the integral of the angular spectrum, which is decomposed into TE and TM waves.
從矢量衍射理論出發(fā)，將入射到固體浸沒透鏡（SIL）底面的光場(chǎng)看成角譜積分形式，并將角譜分量分解為TE波和TM波，從而用隧道薄膜的特性矩陣方法求出相應(yīng)的反射角譜分量。

When diffraction problems are solved by the angular spectrum theory, high speed and high accuracy can be obtained, especially for near-field Fresnel diffraction.
用角譜理論來處理衍射光場(chǎng)，不僅速度快，而且在處理近場(chǎng)菲涅耳衍射光場(chǎng)時(shí)的準(zhǔn)確度是其它方法無法比擬的。
