Equation

$$r_\parallel\equiv\left(\frac{E_{0r}}{E_{0i}}\right)_\parallel \\ r_\perp\equiv\left(\frac{E_{0r}}{E_{0i}}\right)_\perp \\ t_\parallel\equiv\left(\frac{E_{0t}}{E_{0i}}\right)_\parallel \\ t_\perp\equiv\left(\frac{E_{0t}}{E_{0i}}\right)_\perp$$

Latex Code

                                 r_\parallel\equiv\left(\frac{E_{0r}}{E_{0i}}\right)_\parallel \\ 
            r_\perp\equiv\left(\frac{E_{0r}}{E_{0i}}\right)_\perp \\ 
            t_\parallel\equiv\left(\frac{E_{0t}}{E_{0i}}\right)_\parallel \\ 
            t_\perp\equiv\left(\frac{E_{0t}}{E_{0i}}\right)_\perp

Explanation

If an electromagnetic wave hits a transparent medium part of the wave will reflect at the same angle as the incident angle, and a part will be refracted at an angle according to Snell's law. It makes a difference whether the E field of the wave is \perp or w.r.t. the surface. When the coefficients of reflection r and transmission t are defined as. I will briefly introduce the notations in this formulation.

  • : reflected amplitude
  • : transmitted amplitude
