Abstract
In this paper, complex Morlet wavelet transform is introduced to analyze the mode character and the group velocity dispersion of the metallic cylindrical waveguide in the THz time-domain spectroscopy system. The result shows that the dominant mode TE11 is separated from the higher mode, and its intension is above 90% of the total. This analysis method is universal for any THz time-domain spectroscopy system.
