The process includes creating an emulsion of organic liquid dispersed in water, followed by infiltrating the emulsion into the media. At least the second plate includes a fastening interface provided with an aperture. Making many microreflector trios each of which consists of micro-reflectors arranged adjacent to each other and on any imaginary lines Ki to Ki2, each of the trios has micro-reflectors are located generally on a straight line. The pockets are adapted for selectively receiving respective heat packs designed for emitting heat to predetermined targeted regions of the body.
