Abstract
Some embodiments include a thermal ground plane comprising a first and second casing with folding and non-folding regions. The thermal ground plane may also include a vapor structure and a mesh. The mesh may be disposed on an interior surface of the second casing and the mesh include a plurality of arteries extending substantially parallel with a length of the thermal ground plane. The folding region of the first casing may have an out-of-plane wavy structure. The valleys and peaks of the out-of-plane wavy structure, for example, may extend across a width of the first active region substantially parallel with a width of the thermal ground plane.
