Firstly the focused incident beam is decomposed into a spectrum of plane waves, and the amplitude vector of each plane wave is acquired.
首先将入射的聚焦光束分解为平面波谱,得到每个平面波的振幅矢量;As the plane wave travels along, the pattern oscillates rapidly, causing it to emit ultraviolet radiation that the researchers observe.
当平面波行进时,干涉的图样会快速振荡,因而放射出紫外线,研究人员便可以观测得到。A special type of unsteady motions which bear a resemblance to plane wave solutions of the linear theory of elasticity can be constructed.
一种特殊类型的、和线性弹性理论中的平面波解有点相象的非稳态运动可以建立起来。The full-vector plane-wave method was used to calculate the band gaps of the photonic crystal fiber with triangular structure.
用全矢量平面波法计算三角结构光子晶体光纤的带隙。The description of a plane wave diffracted by a circular aperture is directly started from the Maxwell's equations.
平面波经圆孔光阑衍射的表征是直接基于麦克斯韦方程组。Keep in mind that an idealized monochromatic plane wave must be depicted as an infinite wave train .
要记住,一个理想的单色平面波应当表述为一个无限的波列。Therefore, these equations with vanishing body forces cannot admit plane wave solutions under an arbitrary initial state of stress.
因此,这些方程当彻体力为零时,在任意的初始胁强状态下并不具备平面波解。When an inhomogeneous plane wave is introduced into a dense dielectric layer, it can bounce between the two boundaries.
把一非均匀平面波引进折射率较高的介质层时,它会在上下界面间来回地“弹”射。The path length refractor, however, can generate planar wavefronts over a wide operating band.
然而,路径长度折射镜能够在宽频带范围内产生平面波。
