Super-Precise Scale Bar for Reflection-Type THz Imaging
The reflection of terahertz wave from a metallic surface with subwavelength periodic structure was investigated experimentally and theoretically. It is shown that the spatial resolution of the reflection image can be increased drastically due to excitation of spoof surface plasmon polaritons. Theore...
