| Abstract | Negative refraction occurs in Meta- materials which have simultaneous negative permittivity e and permeability μ. In the present communication, it has been shown that photonic crystals (PCs) may also exhibit negative refraction, although they have a periodically modulated positive permittivity e and permeability μ. We have theoretically studied the negative refraction in one-dimensional (1D) photonic crystals (PCs) consisting of dielectric Na3AlF6 with Ge. By using transfer matrix method and Bloch theorem, we have studied the photonic band structure and group velocity, and with the help of group velocity, we have obtained the frequency bands of negative refraction. We found that negative refraction may occur near the low frequency edge of the even band gaps. |
