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…
Unveiling spin-orbital angular momentum locking in photonic Dirac vortex cavities
Haitao Li, Jiusi Yu, Jiayu Fan +6
Dirac vortices, originally studied in quantum field theories to predict localized zero-energy modes, were recently realized in photonics, leading to Dirac vortex cavities. With top…
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…
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…
