Abstract
A technique to study the transmission and backscattering of metallic fiber distributions at submillimetric wavelengths under well controlled laboratory conditions is described. The samples were fabricated on silicon wafers using well established photolithographic techniques. Different types of computer generated fiber distributions were tested. The precision and uniformity in fiber shape and distribution were excellent. The transmission measurements agreed well with the calculated values in many cases. However, the model used does break down when the radius of the fibers is a sizable fraction of the wavelength. It was shown how a given number of fibers are more efficient attenuators when distributed independently than arranged in arrays of 5 fibers. A detailed account of the results and experimental techniques is presented.
