Photoswitchable exceptional points derived from bound states in the continuum
Lei Wang, Hang Liu, Junwei Liu +11
Bound states in the continuum (BICs) and exceptional points (EPs), as two distinct physical singularities represented by complex frequencies in non-Hermitian systems, have garnered…
Frequency-selective terahertz wave amplification by a time-boundary-engineered Huygens metasurface
Fu Deng, Fengjie Zhu, Xiaoyue Zhou +7
Ultrafast manipulation of optical resonance can establish the time-boundary effect in time-variant media leading to a new degree of freedom for coherent control of electromagnetic…
Physics-informed Inverse Design of Multi-bit Programmable Metasurfaces
Yucheng Xu, Jia-Qi Yang, Kebin Fan +8
Emerging reconfigurable metasurfaces offer various possibilities in programmatically manipulating electromagnetic waves across spatial, spectral, and temporal domains, showcasing g…
Terahertz Nonlinear Superconducting Metamaterials
Caihong Zhang, Biaobing Jin, Jiaguang Han +7
We investigate the nonlinear effect of a planar superconducting metamaterial made from niobium nitride (NbN) at terahertz frequencies. As the variation of the incident intense tera…
High-Q terahertz metamaterial from superconducting niobium nitride films
C. H. Zhang, J. B. Wu, B. B. Jin +5
We present in this letter terahertz (THz) metamaterials with low ohmic losses made from low-temperature superconductor niobium nitride (NbN) films. The resonance properties are cha…
Low Loss and Magnetic Field-tuned Superconducting THz Metamaterial
Biaobing Jin, Caihong Zhang, Sebastian Engelbrecht +8
Superconducting terahertz (THz) metamaterial (MM) made from superconducting Nb film has been investigated using a continuous-wave THz spectroscopy with a superconducting split-coil…
