Abstract

Several promising applications of terahertz spectroscopy and imaging techniques in biological and medical diagnostics have been investigated over the years. Polarimetric systems are useful for enhancing imaging contrasts, yet the interplay between THz polarization and the discrete structures in biological samples is still obscure. In this work, we performed Monte Carlo simulations of the propagation of the THz waves in tissues with intrinsic random structures. The polarization states of backscattered THz radiation are obtained for different conditions and their connections are analyzed. This approach can be used to guide the design of the imaging modality and the interpretation of data in future THz applications.
