1. A composite material with adjustable spectral properties comprising:
an elastomeric matrix characterized by an elastomer thickness and comprising an IR-transparent, flexible, and stretchable material characterized by an elastic modulus;
a plurality of micro-domains overlaying the elastomeric matrix, the plurality of micro-domains being characterized by a micro-domain thickness and comprising an IR-reflecting material;
a plurality of spacings, separating the plurality of micro-domains, the plurality of spacings comprising the elastomeric matrix having no overlaid IR-reflecting material;
wherein the plurality of spacings is dynamically adjustable via mechanical manipulations of the elastomeric matrix.
