  • Abstract
    This work extends our study of highly collinear composites to use nanorod materials as a means of providing impedance matching. We have fabricated nanorod (300nm diameter 0.5mm length) materials having high regularity (diameter and spacing) that are highly collinear (rods continuous from face to face of the sample). A comparison is made to conventional loaded epoxy. We find in experimental work that for the nanorod material there was no observable transmission frequency dependence up to 120MHz, by comparison we find loaded epoxy is very sensitive to frequency.
