We describe measurements of single-cycle terahertz pulse propagation in a random medium. The unique capabilities of terahertz time-domain spectroscopy permit the characterization of a multiply scattered field with unprecedented temporal resolution. With these results, we can develop a framework for understanding the statistics of broadband laser speckle. We also describe recent measurements of the polarization dynamics of these diffusively propagating waves. In the diffusive regime, we observe a spectral shift between orthogonal polarization components. This is a result of the strong frequency-dependence of the mean free path within the bandwidth of the THz pulses.
