| 摘要 | This report details image reconstruction of buried dielectric cylinders coated on a conductor by transverse electric (TE) wave illumination. Dielectric cylinders with known cross-section coated on a conductor of unknown permittivities are buried in one half-space and scatter a group of unrelated TE waves incident from another half-space where the scattered field is recorded. Proper arrangement of the various unrelated incident fields avoids the problems of ill-posedness and nonlinearity, and the permittivity distribution can be reconstructed through simple matrix operations. The algorithm is based on the moment method and the unrelated illumination method. Numerical results are given to demonstrate the capability of the inverse algorithm. Good reconstruction is obtained, even in the presence of additive Gaussian random noise in measured data. In addition, the effect of noise on the reconstruction result is also investigated. |
