英文摘要： The universal calculation methods are developed and improved in this project,which are sutitable for three-dimensional fractal plasma photonic crystals. It make the new PWE, FDTD and FDFD method can better calculate the dispersion relation and the energy reponse relationship. The electromagnetic tuning properties of band gap are systematically analysed, and the theories and methods for designing the tunable, high-performance,miniaturized three-dimensional plasma photonic crystals are obtained. From an engineering reality, the influence of the production of random and deformation on the electromagnetic properties are considered. The fractal mathematical theories introduced to the three-dimensional plasma photonic crystals is further explored, which provide a new support to design the new, high-performance microwave photonic crystal devices and fill gaps in the theory. The properties of three-dimensional fractal plasma photonic crystals are comprehensive studied as the direction of magnetic field is arbitrary and the new specific materials (such as non-linear medium, electrical dispersion medium, magnetic dispersion medium) are introduced. Especially,the nonlinear effects of the three-dimensional nonlinear fractal plasma photonic crystal also are studied.The validation experiments of the electromagnetic properties
