  Theoretical and computational study of reflection and refraction of
electromagnetic waves with $p$-polarized and normal incidence electric wave
amplitude vector on anisotropic, inhomogeneous and linear medium has been done.
  The medium used in this study is a model of susceptibility in the form of
rank-2 tensor which its value depends on the frequency, position and time.
Theoretical and computational formulation of transmittance and reflectance are
then tested using vacuum and FeF$_2$ magnetic material.
