摘要

The scale measurement has a great significance in studying electromagnetic scattering properties. But there still exist great difficulties in constructing an accurate scale model including nonmetallic materials such as magnetic absorbing coatings. Based on the reflective loss of a coating irradiated obliquely by plane microwave, a method is proposed to solve the problem of designing the scale coating. The commercial simulation software FEKO is used to investigate the use of the method. According to simulating monostatic RCS of coating plate models, coating sphere models and coating spherecone models, results reveal that the monostatic RCS of the designed scale model have a great agreement with that of the theoretical scale model in the whole incidence angle range. Furthermore, the coating SLICY models, which include many electromagnetic scattering mechanisms, are constructed to verify the proposed method. The simulated result of the designed scale SLICY model is very close to that of the theoretical scale SLICY model. All the simulated results indicate that the method proposed in this paper is valid.
