Control of Spoof Localized Surface Plasmons Using Terahertz Near-field Microscope
説明
We performed time-resolved terahertz near-field imaging of a gold disk with sub-wavelength periodic grooves and successfully observed spoof localized surface plasmons. A selective excitation method is also demonstrated with orbital angular momentum of light.
