Abstract: An interconnection system suitable for transmission lines, in the form of electrical or optical conductors, or in the form of conduits for electrical waveguide transmission, reflected light or fluidic signals, wherein lengths of such transmission lines bridge between discrete point-to-point location on a substrate, the transmission lines being anchored by sealant and filler material at selected substrate locations and being cut generally transversely, or otherwise transversely formed, to provide exposed conductor or conduit end portions anchored at the selected locations. The transverse areas of the conductors or conduits defined by such transversely cut, or otherwise transversely formed, and exposed end portions provide energizable signal energy planes. More specifically, such discrete energizable planes in the form of transverse conductor surfaces, are of a size and shape conforming to the transverse conductor areas exposed by cutting or other forming operation.
