The optical path difference of two rays in the condition of near axis is discussed in the single spherical surface refraction.

本文讨论了单球形折射面在傍轴条件下二相邻光束的光程差问题。

As extension of the back-projection, a concept of spherical back-projection(SBP)is proposed, and then a SBP algorithm is presented to reconstruct near-field microwave images of conducting objects.

作为CT中背投影响的推广，给出了球背投影的概念，进而提出了由散射近场重建理想导体目标轮廓的球背投影法及其实现算法。

The most prevalent way to calculating T-matrix is the extended boundary condition method (EBCM), which, however, is largely limited to axisymmetric and near-spherical particles.

在计算T矩阵的方法中，最流行的方法称之为扩展边界法（EBCM），但是它很大的程度上只适合轴对称和近似球形的粒子。
