Breaking the trade-off between invisibility and sensitivity in electromagnetic sensing
Yichao Liu, Jiaxue Zhou, Weifeng Han +6
Weak electromagnetic signals demand highly sensitive sensors, yet increasing a sensor's sensitivity inevitably strengthens its interaction with the surrounding field, producing sca…
Topological-Charge-Enabled Photonic Doping in ENZ Media
Zhicheng Xiong, Fei Sun, Weiqi Yuan +4
Conventional photonic doping schemes predominantly employ circular or rectangular dielectric dopants with zero topological charge, where the effective permeability can only be tune…
Cloaking of Arbitrarily Shaped Large-Scale Objects Through the Injection of Electromagnetic Invisibility Genes
Zirui Xie, Fei Sun, Yichao Liu +3
Full-space electromagnetic invisibility mainly includes light-bending and scattering-cancellation cloaking. Light-bending cloaking causes double-blind phenomenon and is incompatibl…
Deep Learning-Enabled Invisible Electromagnetic Scattering Amplifier
Qike Xie, Qin Liao, Xiaofan Ji +2
With the rapid development of micro-electro-mechanical systems, electrically small micro-targets, such as subwavelength micro unmanned aerial vehicles and bionic mosquito robots, e…
True Bound States in the Continuum in Compact All-Dielectric Structures
Yiyun Yan, Yichao Liu, Fei Sun +1
Bound states in the continuum (BICs), known for their theoretically infinite quality (Q) factors and strong field localization, hold great promise for high-performance photonic dev…
Broadband Simultaneous Beam Steering and Compressing Device Based on Subwavelength Protrusion Metallic Tunnels
Dongguo Zhang, Fei Sun, Qin Liao +2
Beam steering and beamwidth compressing play a role in steering the beam and narrowing its half-power beamwidth, respectively, which are both widely applied in extending the effect…
Implementation of ultra-broadband optical null media via space-folding
Yichao Liu, Jiale Li, Fei Sun +3
Optical null medium (ONM) has garnered significant attention in electromagnetic wave manipulation. However, existing ONM implementations suffer from either narrow operational bandw…
Broadband source-surrounded cloak for on-chip antenna radiation pattern protection
Hanchuan Chen, Fei Sun, Yichao Liu +3
As the frequency range of electromagnetic wave communication continues to expand and the integration of integrated circuits increases, electromagnetic waves emitted by on-chip ante…
Three-dimensional magnetic cloak working from DC to 250 kHz
Jianfei Zhu, Wei Jiang, Yichao Liu +4
Invisible cloaking is one of major outcomes of the metamaterial research, but the practical potential, in particular for high frequencies (e.g., microwave to visible light), is fat…
Experimentally demonstrated an unidirectional electromagnetic cloak designed by topology optimization
Lu Lan, Fei Sun, Yichao Liu +2
Electromagnetic invisible devices usually designed by transformation optics are rather complicated in material parameters and not suitable for general applications. Recently a topo…
First experimental demonstration of an isotropic electromagnetic cloak with strict conformal mapping
Yungui Ma, Yichao Liu, Lu Lan +4
In the past years quasi-conformal mapping has been typically used to design broadband electromagnetic cloaks. However, this technique has some inherit practical limitations such as…
