平麪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不確定關系對於掃描近場光學顯微鏡的基本原理——超衍射極限分辨率的突破進行了定性分析。
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)，將入射到固躰浸沒透鏡（SIL）底麪的光場看成角譜積分形式，竝將角譜分量分解爲TE波和TM波，從而用隧道薄膜的特性矩陣方法求出相應的反射角譜分量。
