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…
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 planar electromagnetic hyper-lens with uniform magnification in air
Ran Sun, Fei Sun, Hanchuan Chen +2
A planar hyper-lens, capable of creating sub-wavelength imaging for broadband electromagnetic wave, is designed based on electromagnetic null medium. Subsequently, a scheme for the…
Tunable uniform field enhancement in a subwavelength air pillar by photonic doping in epsilon-near-zero medium
Fei Sun, Jinyuan Shan, Yichao Liu
In this study, a novel electric field compressor is proposed by doping a metal-air-metal pillar in epsilon-near-zero medium within a metallic waveguide, which effectively enhances…
On-chip omnidirectional electromagnetic-thermal cloak
Yichao Liu, Hanchuan Chen, Gang Zhao +1
Simultaneously guiding electromagnetic waves and heat flow at any incidence angle to smoothly bypass some electromagnetic/thermal sensitive elements is a key factor to ensure effic…
Simultaneously realizing thermal and electromagnetic cloaking by multi-physical null medium
Yichao Liu, Xiaomin Ma, Kun Chao +6
Simultaneously manipulating multiple physical fields plays an important role in the increasingly complex integrated systems, aerospace equipment, biochemical productions, etc. For…
