Contrast Source Inversion-Based Multilayered Object Analysis for Terahertz Wave Imaging

A complex permittivity profile reconstruction for multilayered objects was presented in this study by incorporating compressed sensing (CS)-based thickness estimation with contrast source inversion (CSI) non-linear inverse scattering (IS) method using a terahertz (THz) frequency band. Several studie...
