Research on Properties of Light Field Localized State in One-dimensional Photonic Crystals

In this paper,the analytic expression of transmissivity and field intensity distribution of photonic crystals at arbitrary incidence angle was given.The effects of absorbing coefficient on the transmissivity and electric field distribution were studied respectively.Otherwise,the effects of different defect model refractive index,incident angle,period number and structure form of photonic crystals on the field intensity distribution were researched,obtaining some new and valuable results.
