Collecting components gives the following two equations.  %  \begin{equation}  m_{1} \left(  E_{\parallel\mathrm{i}} -m_{1}  E_{\parallel\mathrm{r}} \right)  = m_{2} E_{\parallel\mathrm{t}} \end{equation}  %  \begin{equation}  m_{1}E_{\perp\mathrm{i}}  \cos \theta_{1} \left( E_{\perp\mathrm{i}}  -m_{1}  E_{\perp\mathrm{r}} \cos \theta_{1} \right)  = m_{2}E_{\perp\mathrm{e}} +  \cos \theta_{2} E_{\perp\mathrm{e}}  \end{equation}
