【 摘 要 】

We consider the electromagnetic inverse problem for a point source above an inhomogeneous dissipative slab of permittivity-epsilon(z) and conductivity-sigma(z), where z is the depth. Two inversion algorithms based on the invariant imbedding equations derived in previous work are used to reconstruct both the permittivity and the conductivity. Both algorithms use two-sided reflection data and one of them also uses transmission data. Results are presented for clean and noisy data.
