Question

Region 1 ($z<0$) contains a dielectric for which $epsilon_r = 2.5$ while region 2 ($z>0$) is characterized by $epsilon_r = 5$. Let $vec{E_1} = -hat{a}_x 10 - hat{a}_y 15 + hat{a}_z 20$ (V/m). Find the angle that $vec{E_2}$ makes with the surface normal.

Step 1

Given E = -6, -6, 15 + 0.20 (V/m), the tangential component is given by E_t = -6, -6, 15. Therefore, E_t = -6, -6, 15. Show more…
