Analysis of a Nonlinear Technique for Microwave Imaging of Targets Inside Conducting Cylinders

Microwave imaging of targets enclosed in circular metallic cylinders represents an interesting scenario, whose applications range from biomedical diagnostics to nondestructive testing. In this paper, the theoretical bases microwave tomographic inside pipes are reviewed and discussed. A nonlinear quantitative inversion technique non-Hilbertian Lebesgue spaces is then applied kind problem for first time. The accuracy obtained dielectric reconstructions assessed by numerical simulations canonical cases, aimed at verifying dependence result on size conducting enclosure comparing results with conventional free space case. Numerical show benefits lossy environments, although presence type resonances should be carefully taken into account.
