Electrical And Magnetic Properties Of Complex Media

It has practical and theory value to analyze electromagnetic scattering from the complex medium target in the project. Complex materials include chiral, anisotropic and bi-anisotropic media. In the complex materials, the bi-anisotropic media is the most general linear material with complicated characteristic .Especially, the process of producing the complex material is difficult, high cost and long period. So, it is needed to employ the analysis of electromagnetic .Recently, analysing scattering from the complex material targets has become more and more popular with the development of computers and modern science and technologies.Firstly, the paper introduced the character of the ferrite and simulated electromagnetic characteristic of the circulator based on the finite element method (FEM); Nextly, the paper studied the formula which can be used in anisotropic, bi-isotropic, bi-anisotropic materials, such as ferrite,plasma,chiral and so on , achieving unity modeling of complex materials. Further more, based on FEBI(Finite element boundary integral method),the paper also analyze the character of electromagnetic scattering from complex medium target in a free space .With the requirement of unity modeling between target and environment , the paper also studied scattering from complex materials target above a lossy half space , and introduced the curve basic function .Consequently, the curve basic function could supply an effective approach for modeling target which has bigger curvature . Lastly, the paper also studied the reflection coefficient of the PEC plate covered plasma , which changes with the parameters of the plasma. In this paper, the numerical results are in agreement with the published data.
