The Obtaining of Regular Metal and Dielectric Microstructures Based on Irradiation–Modified Polymer Films.

Abstract—Based on regular porous polymeric membranes, the synthesis of metal and dielectric spearhead structures with given morphological characteristics was carried out. Copper structures with the ~1 μm height and dielectric spearhead microstructures made from iodic acid with the 12 μm height and 1 μm diameter were obtained. The possibility is discussed of using such optical elements to solve the problems of increasing the efficiency of IR radiation detection, signal amplification and conversion to visible and near-infrared ranges.
