Theory for Active Thermal Control: Thermal Dipole Effect

Abstract

AbstractIn this chapter, we establish a theory for thermal-dipole-based thermotics. Tailoring the thermal dipole moment allows thermal invisibility without the requirements of singular and uncommon thermal conductivities. Furthermore, finite-element simulations and laboratory experiments both validate the theoretical analyses. Thermal-dipole-based thermotics offers a distinct mechanism to achieve thermal invisibility and provides guidance to other physical fields, such as electrostatics, magnetostatics, and particle diffusion. These results also pave the way for heat regulation with thermal dipoles, and potential applications can be expected in thermal protection, infrared detection, etc.
