摘要
对微波单缝衍射实验仪器和实验数据进行了分析,建立了微波分光计衍射理论模型,并对其进行了数值模拟计算,发现衍射曲线是单缝和发射源前的矩形喇叭口2次衍射叠加的结果,且与数值模拟计算结果吻合相当好.
In this paper, a microwave single-slit diffraction experiment apparatus is introduced and the experimental data are analyzed. A theoretical model of microwave spectrometer diffraction is also established. Numerical simulation shows that the diffraction curve is a superimposition of the diffraction of the single-slit and the rectangular trumpet. The experimental result agrees well with the numerical simulation.
