摘要

Measurement resolution is one of the most important elements for industrial applications. However, conventional lenses for terahertz (THz) or millimeter-wave cannot achieve high resolution due to the diffraction limit. Here, we demonstrate two types of super-oscillatory lenses that are very effective for sub-diffraction focusing at THz.
