Surface currents, scattering, and applications in the Rayleigh region

Extended Maue integral equations for determining the surface magnetic fields and currents are developed and applied for points of discontinuous and continuous surface normal. Methods using the associated integral operators are shown to be useful in obtaining solutions which otherwise might not be tractable. Application is made to evaluate the total surface current on a perfectly conducting sphere for general plane wave incident fields. The dyadic result becomes, at normal incidence, proportional to the incident surface current, which, in all cases of field incidence, has a Rayleigh region limiting value of 3/2. The nature of the dyadic result is examined and the behavior of the limiting current ratio is briefly treated for nonspherical shapes including its deviation from 3/2 for near-spherical shapes.     

背向受激瑞利散射的理论研究

提出一个新颖的模型来描述受激散射过程.由于光与介质相互作用会引起介质内折射率变化,我们引入德拜弛豫关系来描述折射率对光场的响应,通过求解非线性耦合波方程得到了受激瑞利散射的增益因子,并分析了德拜弛豫常数对二波之间能量耦合的影响,以及导致解受激散射的各种物理机制.     

Comments On "Testing a Sample Population for the Rayleigh Distribution" and a Succeeding Correction

In a recent correction [2] to previous correspondence [1] it was stated that 3) of the theorem in [1] was invalid due to the statistical dependence of the yi. The joint distribution function of the yiis derived below confirming their dependence, but also upholding the validity of Item 3. Furthermore, an exact goodness of fit test for the Rayleigh distribution based upon theN + 1observationsx_{1}, ... , x_{N+1}is suggested.     

Correction to "Surface Electromagnetic Modes of a Ferrite Slab" (Letters)

In the above paper, (23) is incorrectly referenced. The correct reference should be [4]. A second error appears on page 760 in the second sentence of the paragraph beginning immediately above Fig. 2. In this sentence the words "dynamic" and "magnetostatic" should be interchanged. The authors wish to thank J. Sethares of the Air Force Cambridge Research Laboratories for bringing the latter error to their attention.     

用瑞利散射激光雷达探测平流层中上部温度

介绍了一台用于平流层中上部温度探测的双波长激光雷达 ,分析了数据处理方法及其过程。该激光雷达获得的结果与NOAA NMC及MSISE 90模式资料对比表明 ,在 30～ 40km高度范围内三者反映了较一致的温度分布特征。一般情况下 30～ 40km范围内它们的温度偏差小于 3K ;低层 30km以下很可能主要受气溶胶的影响 ,相对偏差小于 6K。
