Abstract
A device for reflecting electromagnetic energy is produced by introducing a dispersion of discrete electromagnetically reflective particles into a volume of uncured thermoplastic resin which allows the radiation to pass therethrough. The particles are deposited onto one surface of the layer of the resin and may be allowed to migrate, through the influence of gravity, toward the other surface thereof to form a strata which reflects electromagnetic radiation passing through the thermoplastic layer. Alternatively, the reflective particles may assume a distributed state within the uncured resin and a sheet of wire mesh or metal coated fabric may be introduced into the resin in order to aid in establishing the electrical continuity between the particles required to reflect the electromagnetic energy. The resin is then cured to fix and protectively cover the reflective particles. The reflector device may be produced in a flat sheet and then formed to the desired shape or may be produced in a mold conforming to the final configuration.
