Gupta, Manoj; Singh, Ranjan, 2021, "Replication Data for: Terahertz Sensing with Optimized Q/Veff Metasurface Cavities", https://doi.org/10.21979/N9/SRDC9A, DR-NTU (Data), V1, UNF:6:1U/9Po6a5ClppS0honp8Jw== [fileUNF]
Confinement of electromagnetic radiation in a subwavelength cavity is an important platform for strong light–matter interaction as it enables efficient design of photonic switches, modulators, and ultrasensitive sensors. Metallic metasurfaces consist of an array of planar cavitie... |

Gupta, Manoj; Savinov, Vassili; Xu, Ningning; Cong, Longqing; Dayal, Govind; Wang, Shuang; Zhang, Weili; Zheludev, Nikolay I.; Singh, Ranjan, 2020, "Replication Data for: Sharp toroidal resonances in planar terahertz metasurfaces", https://doi.org/10.21979/N9/UWBOGJ, DR-NTU (Data), V1
Toroidal dipole excitation in planar metasurface provides an alternate approach towards excitation of high Q resonances. In contrast to conventional multipoles, toroidal dipole interaction strength depends on the time derivative of the surrounding electric field. A characteristic... |

Gupta, Manoj; Singh, Ranjan, 2020, "Replication Data for: Toroidal versus Fano resonances in high Q planar THz metamaterials", https://doi.org/10.21979/N9/5RYPXN, DR-NTU (Data), V1
Radiative losses are crucial in optimizing the performance of metamaterial based devices across the electromagnetic spectrum. Introducing structural asymmetry in meta-atom design leads to the excitation of sharp Fano resonances with reduced radiative losses. However, at larger as... |

Gupta, Manoj; Srivastava, Yogesh Kumar; Manjappa, Manukumara; Singh, Ranjan, 2020, "Replication Data for: Sensing with toroidal metamaterial", https://doi.org/10.21979/N9/UOBJPK, DR-NTU (Data), V1
Localized electromagnetic excitation in the form of toroidal dipoles has recently been observed in metamaterial systems. The origin of the toroidal dipole lies in the currents flowing on the surface of a torus. Thus, the exotic toroidal excitations play an important role in deter... |
