[EN] Beam profiling in terahertz systems based on a 4f configuration is revised to show that usual practices underestimate the beam waist due to the narrow point spread function of the detection arm. A rigorous assessment ...

[EN] In this paper, an iterative algorithm is developed
to combine time shifted traces in pulsed terahertz time domain
spectroscopy (THz-TDS). This method intends to correct
errors due to mechanical sampling in the trailing ...

[EN] A new technique for terahertz time-domain ellipsometry is presented. Information of reflection coefficients of the sample in two orthogonal polarizations is encoded on the same terahertz trace by using a birefringent ...
