Recovering lossless propagation of polaritons with synthesized complex frequency excitation
Fuxin Guan, Xiangdong Guo, Shu Zhang +8
Surface plasmon polaritons and phonon polaritons offer a means of surpassing the diffraction limit of conventional optics and facilitate efficient energy storage, local field enhan…
Synthesized complex-frequency excitation for ultrasensitive molecular sensing
Kebo Zeng, Chenchen Wu, Xiangdong Guo +7
Detecting trace molecules remains a significant challenge. Surface-enhanced infrared absorption (SEIRA) based on plasmonic nanostructures, particularly graphene, has emerged as a p…
Gauge Field Induced Chiral Zero Mode in Five-dimensional Yang Monopole Metamaterials
Shaojie Ma, Hongwei Jia, Yangang Bi +5
Owing to the chirality of Weyl nodes characterized by the first Chern number, a Weyl system supports one-way chiral zero modes under a magnetic field, which underlies the celebrate…
Overcoming losses in superlenses with synthetic waves of complex frequency
Fuxin Guan, Kebo Zeng, Zhaoyu Nie +6
Superlenses made of plasmonic materials and metamaterials have been exploited to image features of sub-diffractional scale. However, their intrinsic losses impose a serious restric…
