This article is about simulation design for SUPW to travel normal incidence to ideal conductor’s surface. I study the question of SUPW’s normal incident to the surface between two media. Then, discuss the case where one of the two media is ideal conductor. I determine the amplitude relation, phase relation about incident wave and reflect wave, obtain the expressions of incident wave, reflect wave and compound wave. Lastly, I use MATLAB to draw the wave diagram of electric field and magnetic field.
