  Active metadevices with external excitations exhibit significant potential
for advanced heat regulation. Nonetheless, conventional inputs, like
heating/cooling and introducing convection by rotating plate, display inherent
limitations. One is the only focus on far-field control to eliminate
temperature distortion in the background while neglecting near-field regulation
in the functional region. Another is lacking adaptability due to complex
devices like thermoelectric modules and stepping motors. To tackle these
challenges, the concept of diffusive superimposed dipoles characterized by
orthogonal thermal dipole moments is proposed. Cooperative near- and far-field
regulation of temperature fields is achieved by designing superimposed dipole
moments, enabling transparency and cloaking functionalities. Simulation and
experiment outcomes affirm the efficacy of this adaptive thermal field control
technique, even when interface thermal resistance is taken into account.
Adaptivity stems from dipole moment decomposability, allowing metadevices to
operate in various heat flux directions and background thermal conductivity.
These findings could pave the way for cooperative and adaptive thermal
management and hold potential applications in other Laplace fields, including
direct current and hydrodynamics.
