Abstract: The plane wave expansion method is used to explore the photonic band-gap characteristics of two kinds of photonic crystal structure under rotation operation. First, constructed two different kinds of photonic crystal structure and compared the difference of the band-gap characteristics of these two kinds of structure. Discussed the effect of the rotation operation on the band gap of two kinds of structure in TE mode respectively, found that the distribution of medium column in x-z plane together influence TE mode band gaps. According to the result of calculation, analyze the reason of the influence on the band gap characteristics, and give the angle range of the optimum band gap. It has better theoretical guiding significance on producing photonic crystal of good performance.
