Fig. 4. (Color online) (a) The two-dimensional image of CW-THz waves transmitted through Sample I with double-void defects of the diameters of 472 µm and 487 µm and the distance of 452 µm. (b) The cross-sectional profile (the black curve) along the yellow dotted line shown in (a) and its double Gaussian fitting (the red curve). The two blue curves indicate each Gaussian components forming the double Gaussian fitting.
