Abstract

We report on an attempt of cooling microsystem surface using a microminiatured heat sink. We also aim to enhance the outward heat flux from a microsystem surface via the radiation, optical (far infrared), and thermal properties of a copper nanostrip array that acts as a bandselective coupler; emitting heat on the surface as non-radiative electromagnetic components (phonon or plasmon polaritons at the surface). The emissivity was controlled with a nanostrip array designed as a pipe organ resonance (vertically) and 2 nd Bragg resonance (horizontally), which generated a temperature gradient of 1.3 K across the substrate thickness when the other side of the substrate was heated to 42°C from room temperature (26°C).
