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…
