Abstract

We describe what are to our knowledge the first measurements of the propagation of coherent, single-cycle pulses of terahertz radiation in a scattering medium. By measuring the transmission as a function of the length L of the medium, we extract the scattering mean free path lsω over a broad bandwidth. We observe variations in ls ranging over nearly 2 orders of magnitude and covering the entire thin sample regime from L/ls1 to L/ls10. We also observe scattering-induced dispersive effects, which can be attributed to the additional path traveled by photons scattered at small angles.
