微波单缝衍射实验中的畸变现象研究

Research on the deformation in single-slit microwave diffraction experiment

介绍了微波单缝衍射实验中出现的畸变现象,研究了单缝宽度、挡板面积、单缝结构、发射喇叭与载物台间距对畸变现象的影响.结合实验对畸变现象进行分析,通过增加单缝宽度和挡板面积、改变单缝结构及发射喇叭与载物台间距可以很好地消除畸变现象,得到与理论图样吻合很好的实验图样.

This article introduces the deformation phenomena in single-slit microwave diffraction experiment, investigates the effects of slit width, baffle size, slit structure and the distance between the bugle and the platform on the deformation phenomena, analyzes the deformation phenomena based on experimental results. The deformation phenomena is eliminated by increasing the slit width and baffle size, and changing the structure of the slit, etc. The obtained diffraction pattern is in accordance with the theoretical prediction.
