Abstract :
We experimentally demonstrate the propagation with minimal distortion and attenuation of broadband, complex THz signals through 137 m of dense fog with an approximate visibility of 7 m. The Mie scattering model is used to calculate the optical visibility, while the Rayleigh model is used to explain the observed THz attenuation.
