—In this paper a new type of optical filter using photonic band gap materials has been suggested.A detailed mathematical analysis is presented to predict allowed and forbidden bands of wavelengths with variation of angle of incidence.It is possible to get desired ranges of the electromagnetic spectrum filtered with this structure by changing the incidence angle of light.
