7-1解答

$\displaystyle \vE^*\cdot \vE$ $\displaystyle = \left\{ \left[ a_1 \bm{\epsilon}_1 + a_2 e^{-i\delta } \bm{\eps...
...\epsilon}_2\right] e^{-i\left(\omega t -\vk\cdot \vr +\delta_1\right)} \right\}$    
  $\displaystyle = \left[ a_1 \bm{\epsilon}_1 + a_2 e^{+i\delta } \bm{\epsilon}_2\...
...ta } \bm{\epsilon}_2\right] e^{-i\left(\omega t -\vk\cdot \vr +\delta_1\right)}$    
  $\displaystyle =a_1^2 +a_2^2$
