Abstract: Nonmaterial deflector-enhanced collector (NDC) is a device in which a nonmaterial, such as electromagnetic (EM) wave, provides a medium in which an obliquely incident nonmaterial (IN) can be intercepted and deflected, so that by proper arrangement, some desired objective can be achieved, such as: deflecting, concentrating, diverging, protecting, receiving, propagating/guiding--by many (fiber-optic-like) deflections--the IN. NDC comprises: a projector of nonmaterial, PON, its projected nonmaterial deflector(s) ND, and (intended) collector or receiver, C or R. The projector projects the ND obliquely towards the incident nonmaterial to be deflected, IN (such as EM radiation) so that this IN is deflected towards an intended receiver--if any is present. It may be necessary to ensure build up of proper optical density gradient, in the vicinity of the ND, to encourage refraction and/or total internal reflection of the IN.
