Next-generation devices for low-latency and seamless communication are envisioned to revolutionize information processing, which would directly impact human lives, technologies, and societies. The ever-increasing demand for wireless data traffic can be fulfilled by the terahertz... |
Song Han; Prakash Pitchappa; Wenhao Wang; Yogesh Kumar Srivastava; Mikhail V. Rybin; Ranjan Singh, 2021, "Replication Data for: Extended Bound States in the Continuum with Symmetry- Broken Terahertz Dielectric Metasurfaces", https://doi.org/10.21979/N9/81VE6S, DR-NTU (Data), V1
Excitation of the non-radiative eigenmodes in photonics and metamaterials above their light cone, that is, the bound states in the continuum (BICs), has drawn fundamental and technological interest. However, the current studies on photonic BICs are mainly restricted to the charac... |
Han, Song; Rybin, Mikhail V.; Pitchappa, Prakash; Srivastava, Yogesh Kumar; Kivshar, Yuri S; Singh, Ranjan, 2021, "Replication Data for: Guided-Mode Resonances in All-Dielectric Terahertz Metasurfaces", https://doi.org/10.21979/N9/E6QQAL, DR-NTU (Data), V1
Coupling of diffracted waves in gratings with the waveguide modes gives rise to the guided mode resonances (GMRs). The GMRs provide designer linewidth and resonance intensity amidst a broad background, and thus have been widely used for numerous applications in visible and infrar... |
