Abstract. This paper presents microwave experiment demonstrating waves passing through a two-dimensional microwave photonic crystal at its different plane orientations. The comparison study of expected microwave transmission behaviour from ray optics standpoint as well as conception of an effective refractive index is carried out. The electric microwave field distribution pattern, available from experiments, is also analyzed. It is shown that the sample studied has a negative effective refractive index at certain orientations and frequencies. 

Keywords: microwave photonic crystal, ray optics, effective refractive index, microwave field visualization.
