Polarized terahertz (THz) waves offer unique advantages for diagnostic medical imaging, but scattering mechanisms in tissue remain unclear. To address this knowledge gap, researchers from Stony Brook University developed a comprehensive model of polarized THz wave scattering from biological structures. Using simulations, tissue phantoms, and porcine skin samples as validation, they showed that microscopic tissue changes can be identified from polarization measurements, offering a promising path for the early detection of cancer.
