Abstract :
We demonstrate end-fire excited THz radiation coupled in thin layers of water propagating a distance of 4 cm. As the propagation lengths are critically dependent from the permittivity, we experimentally demonstrate this propagation length dependency by stepwise exchanging the material layer from deionized water to pure ethanol.
