Abstract
A thermoelectric cloak including an inner region and an external medium. The inner region has a cloaking effect and is simultaneously invisible from both heat and electric charge fluxes; and heat, electric currents, and gradients in the external medium are unaltered by the cloaking effect of the inner region.
Claims16
A thermoelectric cloak comprising:
- an inner region of the thermoelectric cloak, wherein the inner region has an annular shape having an inner radius and an outer radius, wherein the inner region comprises a metamaterial composite having concentric bilayers, wherein an individual concentric bilayer comprises a first layer and a second layer surrounding the first layer, wherein the first and second layers are different homogenous layers;
- and
- an external medium of the thermoelectric cloak, wherein the external medium is located outside the outer radius of the inner radius;
- wherein the inner region has a thermoelectric cloaking effect that isolates an interior cavity surrounded by the inner radius from heat and electric charge fluxes coupled via thermoelectricity in the external medium,
- wherein heat, electric currents, and gradients in the external medium of the thermoelectric cloak are unaltered by the thermoelectric cloaking effect of the inner region of the thermoelectric cloak.

A method comprising:
- fabricating a thermoelectric cloak having an inner region and an external medium of the thermoelectric cloak, wherein the inner region has an annular shape having an inner radius and an outer radius, wherein the inner region comprises a metamaterial composite having concentric bilayers, wherein an individual concentric bilayer comprises a first layer and a second layer surrounding the first layer, wherein the first and second layers are different homogenous layers, wherein the external medium is located outside the outer radius of the inner radius;
- and
- isolating an object from a thermoelectric flow in the external medium by positioning the object within an interior cavity surrounded by the inner radius of the inner region, wherein the inner region has a thermoelectric cloaking effect that isolates the interior cavity surrounded by the inner radius from heat and electric charge fluxes coupled via thermoelectricity in the external medium, wherein heat, electric currents, and gradients in the external medium of the thermoelectric cloak are unaltered by the thermoelectric cloaking effect of the inner region of the thermoelectric cloak.
