Abstract: The electric field distribution formula of the transmitted incident liqut at arbitrary angle in one-dimensional photonic crytals is deduced.The electric field distribution properties of one-dimentional photonic crystals are thus researched.The research shows that the incident angle,permutation of dielectric mode of photonic crystals,defect mode and defect mode refractive index can make different influences on the election field distribution in one-dimensional photonic crystals.

Key words: one-dimensional photonic crystals, electric field distribution, defect mode
