A new multifrequency inverse algorithm is presented based on the improved variational
Born iterative method (VBIM) for 3-D quantitative microwave imaging (MWI). The proposed …

In this article, we have improved the quantitative inversion performance of the cross-
correlated contrast source inversion (CC-CSI) method by incorporating the subspace …

A sparse planar array often suffers from the strong grating-lobes that deteriorate inversion
performance due to spatial undersampling. In this article, a diffraction tomography (DT) …

By leveraging the relation between sampling and sparsity, compressive sensing (CS) has
been developed and applied in many fields, including electromagnetics. In this article, we …
