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…
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…
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…
