查询词典 dimensional equation

The main properties of one-dimensional photonic band gap structures that include layers of negative refraction material are analyzed from the explicit dispersion equation. The results show that the photonic crystals containing negative refraction materials have wider photonic band gaps which is different from the case of traditional photonic crystals with narrow transmission bands when the two layers have the same optical thickness.
