利用特征矩阵法讨论了一维三元光子晶体的偏振特性。结果表明，在一级禁带内，光子晶体对S偏振光形成了全方位光子带隙；对P偏振光，禁带宽度随入射角的增大而减小，且只在禁带短波区域形成全方位光子带隙，而在禁带长波区域，随着入射角的变化将出现透射峰，存在明显的“广义布儒斯特角”，各波长对应的“广义布儒斯特角”随波长增大而减小，透射峰半角宽度增大，透射峰个数逐渐增加。
利用特徵矩陣法討論瞭一維三元光子晶體的偏振特性。結果錶明，在一級禁帶內，光子晶體對S偏振光形成瞭全方位光子帶隙；對P偏振光，禁帶寬度隨入射角的增大而減小，且隻在禁帶短波區域形成全方位光子帶隙，而在禁帶長波區域，隨著入射角的變化將齣現透射峰，存在明顯的“廣義佈儒斯特角”，各波長對應的“廣義佈儒斯特角”隨波長增大而減小，透射峰半角寬度增大，透射峰箇數逐漸增加。

Polarization properties of one-dimensional ternary photonic crystal are studied by using characteristic matrix method, the results showed that, in first-order forbidden band, there was omni-directional photonic band gap in photonic crystal with the incidence of S-polarization, that the forbidden band width decreased with the increase of incidence angle of P-polarization and omni-directional photonic band gap was formed only in the range of short-wave in the forbidden band, however, in the long-wave range of forbidden band, transmission peak appeared with the change of incidence angle and there was an obvious ＂general Brewster angle＂, the ＂general Brewster angle＂ corresponding to each wavelength decreased with the increase of wavelength, semi-angle width of transmission peak increased and the number of transmission peak gradually increased.
