Electromechanically tunable frequency-agile metamaterial bandpass filters for terahertz waves Oct 19, 2021 - Kumar Abhishek Kumar Abhishek, 2021, "Electromechanically tunable frequency-agile metamaterial bandpass filters for terahertz waves", https://doi.org/10.21979/N9/UCSDQF, DR-NTU (Data), V1 Tunable transmission filters are essential for various key terahertz applications including miniaturized spectrometers, hyperspectral imagers and channel selectors in high-speed wireless communication systems. However, tunable terahertz transmission filters have remained elusive,...

Replication Data for: Giant enhancement in Goos-Hänchen shift at the singular phase of a nanophotonic cavity Aug 20, 2021 - Tier 1 RG191/17 Kandammathe Valiyaveedu, Sreekanth, 2021, "Replication Data for: Giant enhancement in Goos-Hänchen shift at the singular phase of a nanophotonic cavity", https://doi.org/10.21979/N9/61WPFK, DR-NTU (Data), V1 In this letter, we experimentally demonstrate thirty-fold enhancement in Goos-Hänchen shift at the Brewster angle of a nanophotonic cavity that operates at the wavelength of 632.8 nm. In particular, the point-of-darkness and the singular phase are achieved using a four-layered me...
