Tamm Cavity in the Terahertz Spectral Range
ACS Photonics, 2020 Electromagnetic resonators, which are based on optical cavities or electronic circuits, are key elements to enhance and control light-matter interaction. In the THz range, current optical cavities exhibit very high-quality factors with $(λ/2)^3$ mode volumes limited by diffraction, whereas resonant electronic circuits show low quality factor but ...

Terahertz Beam Shaping: Gaussian to Flat-top Beam Conversion Through Tri-layer Metasurface
, 2022 A flat-top beam is preferred to a normal Gaussian beam for various imaging applications since it provides more uniform illumination over a scene. In this paper, we present a highly efficient tri-layer metasurface lens for terahertz beam shaping, namely ...

Resonant scattering probes in the terahertz range [PDF]
2017 42nd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2017 We propose and demonstrate a novel near-field probe, resonant at terahertz (THz) frequencies. A conical metal tip, with length 50–1000 μm is fabricated directly to the surface of a semiconductor surface, acting as a radially-polarized THz source. High field confinement is seen at the apex of the probe.

Advanced Functional Materials, EarlyView.In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.
