非均匀介质中反射波的产生

Generation of a reflected wave in an inhomogeneous medium

M. I. Ayzatsky

AI总结:

本文采用广义WKB方法将非均匀介质中的电场分解为两个传播分量,发现所谓左行分量实为递增相位的反射波,可为介质加速波导设计及半经典粒子过势垒反射定位提供依据。

摘要:

在本工作中,我们给出了基于广义WKB方法计算非均匀介质中电场分布的结果。在该方法中,场被表示为两个分量之和,其中一个分量与向右传播的WKB解相关,另一个与向左传播的WKB解相关。研究表明,第二个分量并不是向左传播的非均匀波。计算结果显示,该分量的相位分布具有递增特征,类似于向右传播波分量的相位分布。所得结果可用于介质加速波导的开发。所得结果还可能指示能量高于势垒高度的半经典粒子在何处可从平滑势垒发生反射。

英文摘要:

In this work we present the results of calculation of the electric field distribution in the inhomogeneous media based on the generalized WKB method. In this approach the field is represented as the sum of two components, one of which is associated with the right-travelling WKB solution and the other with the left-travelling WKB solution. It has been shown that the second component is not a left-travelling nonuniform wave. Calculation results showed that the phase distribution of this component has an increasing character, similar to the phase distribution of the right-travelling wave component. Obtained results can be useful during the development of dielectric accelerating waveguides. The obtained results may also indicate the location where a semiclassical particle with energy greater than the barrier height can reflect from a smooth potential barrier.
