However, quantitative reconstruction of high-contrast targets remains a formidable challenge due to severe multiple scattering effects and the inherent ill-posedness of electromagnetic inverse problems. To overcome this fundamental bottleneck in computational microwave imaging, this paper proposes an alternating optimization framework based on cross-correlated physics-informed neural network (Alt-CC-PINN).
