Nonreciprocal Thermal Material by Spatiotemporal Modulation
Nonreciprocal Thermal Material by Spatiotemporal Modulation
The thermal properties of a material with a spatio-temporal modulation in both the thermal conductivity and the mass density are studied. The special configuration studied here consists of a modulation in a wave-like fashion. It is found that these materials behaves, in an effective way, as materials with an internal …
