In a previous paper we described an accurate method for tracking a Gaussian beam incident on a particular diffraction grating. In this paper we use the same method to track a fundamental Gaussian beam at microwave frequency incident upon rectangular and sinusoidal gratings for more general information about the interaction during the process. We extensively study how different parameters of the incident beam such as waist radius, beam frequency, incident angle, polarization direction, and grating depth affect the spatial modifications differently. This study is of great use for designing a millimeter-wave electromagnetic system for example measurements of components for a gyrotron.

矩形和正弦衍射光栅的高斯光束空间修正

在先前的论文中，我们描述了一种跟踪入射在特定衍射光栅上的高斯光束的精确方法。在本文中，我们使用相同的方法以入射在矩形和正弦光栅上的微波频率跟踪基本高斯光束，以获取有关过程中相互作用的更一般的信息。我们广泛研究了入射光束的不同参数（例如腰围半径，光束频率，入射角，偏振方向和光栅深度）如何不同地影响空间修改。这项研究对于设计毫米波电磁系统（例如，回旋管部件的测量）非常有用。
