Numerical analysis and experimental study of terahertz solid immersion microscopy

Terahertz (THz) solid immersion microscopy is a modality of THz imaging, which allows one to overcome the Abbe diffraction limit and provides high energy efficiency due to the absence of subwavelength apertures and probes in an optical scheme. It exploits the effect of a reduction in dimensions of electromagnetic-wave caustic, when it is formed in free space, at a small distance (更多
