MATLAB仿真平面電磁波在不同媒介分界面上的入射

1、.MATLAB仿真平面電磁波在不同媒介分界面上的入射、反射和折射一、實驗?zāi)康模?、 進(jìn)一步學(xué)習(xí)MATLAB，初步掌握GUI界面的編程。2、 通過編程實現(xiàn)電磁波仿真效果圖。3、 進(jìn)一步理解平面電磁波的入射、反射和折射現(xiàn)象二、實驗要求：1、 以電場為例，動態(tài)演示平面電磁波的傳播情況。2、 可以任意設(shè)置媒介的介電常數(shù)和入射角。3、 考慮金屬導(dǎo)體和空氣的分界面平面電磁波的入射、反射情況。三、實驗原理：電磁波從一種媒質(zhì)入射到第二種媒質(zhì)時，分界面使一部分能量反射回第一種媒質(zhì)，另一部分能量折射到第二種媒質(zhì)中，反射波和折射波得大小和相位取決于分界面兩側(cè)的媒質(zhì)特性、極化方向和入射角大小等，當(dāng)電磁波入射到理想導(dǎo)體

2、表面時，會發(fā)生全反射。這一過程中包括的主要原理有以下三點(diǎn)。1、正弦平面波在媒質(zhì)分界面的反射和折射規(guī)律波對分界面的入射是任意的，但為了方便，我們假設(shè)入射面與zox面重合。波在z0時發(fā)生入射和反射，在zx=-xv*sind(sita);y=xv*cosd(sita);x=x+cosd(sita)*yv;y=y+sind(sita)*yv; xv1 = 0:pi/10:20*pi;yv1 = sqrt(1-er*er)*sin(xv-pi/30*i);%x1=xv1*sind(sita);y1=xv1*cosd(sita);x1=x1-2*cosd(sita)*yv1;y1=y1+sind(sita
