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…
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…
Decoupling heat and electricity: A thermal invisible gateway
Jiahao Li, Fei Sun, Yichao Liu +4
The Wiedemann-Franz law couples electrical and thermal conductivity, making high electrical conduction with low thermal conduction a major challenge. To overcome this, we designed…
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…
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…
Thermal superscatterer: amplification of thermal scattering signatures for arbitrarily shaped thermal materials
Yichao Liu, Yawen Qi, Fei Sun +7
The concept of superscattering is extended to the thermal field through the design of a thermal superscatterer based on transformation thermodynamics. A small thermal scatterer of…
