Abstract
A microwave imaging (MWI) system prototype to reconstruct three-dimensional (3D) complex dielectric images of various dielectric phantom models is provided. The imaging cavity of this system is filled with a newly compounded emulsion that provides a long-term stable and a controllable range of background-to-target dielectric contrasts. The system utilizes a tapered patch antenna array that enables multi-frequency operation. The the enhanced variational Born iterative method with bounding constraints (BC-VBIM) is applied as the inverse solver. Multiple experiments with various phantoms are conducted to evaluate the system's performance and imaging capabilities. Phantom models being used in this work for system evaluation include single, double, and multiple spherical targets filled with various water-isopropyl alcohol mixtures and submerged either directly in the background emulsion or within another water-alcohol mixture that is submerged in the emulsion.
