Electric Field Distribution of New One Dimensional Linear Function Photonic Crystals

This paper researches the transmissivity of the one dimensional linear function photonic crystals,and the effect of different period numbers and different optical thickness on the field intensity in photon crystals.Some new results different from the conventional photonic crystals are obtained.When the medium BandArefractive indexes distribution function for linear increase,transmissivity of linear function photonic crystal can be far greater than 1;with the increase of period numbers,the maximum value of electric field strength increases significantly;the change of period numbers can make the magnification of the function photonic crystal field change accordingly.Such results provide theoretical approach and idea for photonic crystals preparation and applications.
