Photonic crystals are a major discovery in physics and have an important infl uence on our present life. The biggest feature of the photonic crystals is it has bandgap which can block photons of a certain frequency, thus affecting the photon movement. This eff ect is like the infl uence of the semiconductor body on electrons. Therefore, research and discovery of the photonic crystal is a broad prospect, people has large expectation on the photonic crystal. The emergence of photonic crystals makes it possible for the miniaturization and integration of some aspects of information technology. Study of structure able to determines characteristics, thus the discovery of the photonic crystal structure and function will lay the foundation for the study of its application, in this paper, the study is focus on the research of material absorption of photonic crystal on Transverse Magnetic (TM) wave band. Firstly, the basic knowledge and principle of photonic crystal are introduced. Then, the research was carried out to study the eff ect of characteristic matrix method on photon crystal TM energy wave through designed experiments and analyzed by computer software.
