A high-Q metasurface signal isolator for 1.5T surface coil magnetic resonance imaging on the go
Qun Ren, Yuxin Lang, Yuqi Ja +8
The combination of surface coils and metamaterials remarkably enhance magnetic resonance imaging (MRI) performance for significant local staging flexibility. However, due to the co…
Evolution Attack On Neural Networks
YiGui Luo, RuiJia Yang, Wei Sha +3
Many studies have been done to prove the vulnerability of neural networks to adversarial example. A trained and well-behaved model can be fooled by a visually imperceptible perturb…
Plug-Play Plasmonic Metafibers for Ultrafast Fiber Lasers
Lei Zhang, Huiru Zhang, Ni Tang +21
Metafibers expand the functionalities of conventional optical fibers to unprecedented nanoscale light manipulations by integrating metasurfaces on the fiber tips, becoming an emerg…
The Physics of Compressive Sensing and the Gradient-Based Recovery Algorithms
Qi Dai, Wei Sha
The physics of compressive sensing (CS) and the gradient-based recovery algorithms are presented. First, the different forms for CS are summarized. Second, the physical meanings of…
