Three-dimensional polarization of thermal fields at arbitrary distances from thin-film emitters
Xiaohong Zhang, Wenshan Cai, Zhuomin Zhang
Recent advances have shown that thermal radiation can exhibit strong polarization in both the near and far fields. However, most existing studies focus on paraxial far-field emissi…

Topologically enhanced optical helicity density in the thermal near field of twisted bilayer van der Waals materials
Xiaohong Zhang, Chiyu Yang, Wenshan Cai +1
Twisted van der Waals (vdW) bilayers can support tunable surface/hyperbolic phonon polariton (S/HPhP) depending on the interlayer twist angle. S/HPhPs can be thermally excited and…
