A dielectric cube, with dimensions of wavelength, was placed at the length of terajet in front of a terahertz detector. Enhancement of the detector responsivity by 4.3 dB with a decrease of noise equivalent power was experimentally demonstrated under excitation of 0.3 THz (see article number 1900700 by Yahya Moubarak Meziani and co‐workers). This opens the way for the development of new THz detectors that could overcome the diffraction limit obstacle.
