✦ Synopsis

The inc,erse scartering of dielectric cylinders buried in a half space is ini.rstigared. Dielectric cylinders of unknown permittiiities are buried in one hulf space and scatter a group of unrelated waL'es incident from unother hulf space uhere the scattered field is recorded. By proper atrangemrnt of the i.arious unrelated incident fields. the difjculties of ill-posedness and nodineany are circumiwted, and the permittivily drstnhirtron can be recoristnrctrd through simple niatrix operations. The iilgorithm is hosed on the moment method and the unrelated illumination mrthod. Numerical results show that good reconstruction has been ohtoined both with and w,ithout Gaussian noise in measured data. C 195% John Wiley & Sons, Inc.

## Abstract The multilevel fast multipole algorithm (MLFMA) is applied to the problem of a general three‐dimensional dielectric target above or below a lossy half space. The dyadic half‐space Green's function is evaluated rigorously for the β€œnear” MLFMA interactions, while an asymptotic Green's fun
