A coating composite is provided for a platform surface of an antenna array for, when applied to the platform, affording isolation of radiating and receiving antennas of the array. The coating composite includes a plurality of conductively coated elongate tubes dispersed in an insulating polymer matrix at a volume loading density approaching that at which the composite begins to conduct electrically over macroscopic distances, i.e., close to the percolation threshold. The tubes are preferably comprised of microtubules comprised of biologically-derived, high-aspect rod-shaped particles of microscopic dimensions having an electroless plated metal coating thereon.

The present invention comprises a writing implement having means to provide for illumination on the writing surface concentrically about implement contact therewith. Replaceable, translucent writing cartridges are envisioned, this as well as a translucent end piece providing an aligning socket for the light bulb. Novel pressure switch means is supplied for selectively energizing the inwardly contained light means so that light illumination will be provided proximate the point of the implement.

Writing device incorporating illuminating means

A flashlight and writing implement combination wherein the device is interiorly illuminated, and ultimately conducts such illumination in either of two directions, depending upon on which end the cap of the implement is placed. The cap includes reflective means for reversing light-flow back through the light-conductive or translucent barrel, toward the end piece and to the writing tip itself, concentrically thereabout. Optionally, the cap is disposed on the reverse end, in which event the light is actuated to send illumination in the opposite direction, the device thereby serving as a flashlight. Aperture means may be provided the cap so that the usually provided clip can be depressed to actuate the pressure switch of the implement. The cap can be made of a resilient deformable plastic material so that by squeezing the same the pressure switch means of the implement may be actuated.
