1. A method of fabricating a multi-mode heat transfer device, the method comprising:
forming a thermal metamaterial composite structure that includes an inner core to radiate heat and an outer core that at least partially surrounds the inner core, the outer core including a high thermally conductive material inlay and a low thermally conductive material matrix that form a composite material pattern to thermally concentrate and direct heat radiated by the inner core to an area outside of the multi-mode heat transfer device, while also thermally cloaking heat radiated by the inner core;
stacking a plurality of thermal metamaterial composite structures in a stacked formation to form a thermal metamaterial composite assembly; and
manipulating the emissivity of the thermal metamaterial composite assembly by selectively applying a coating or a plating to one or more outer surface regions of the outer core to enhance the transfer of heat by the composite material pattern.
