Fourier Synthetic Aperture-based Time-resolved Terahertz Imaging
Vivek Kumar, Pitambar Mukherjee, Lorenzo Valzania +3
Terahertz microscopy has attracted attention owing to distinctive characteristics of the THz frequency region, particularly non-ionizing photon energy, spectral fingerprint, and tr…
