The present invention’s stratified composite system of armor, as typically embodied, comprises a backing stratum and a strike stratum that includes elastomeric matrix material and low-density ceramic elements embedded therein and arranged along a geometric plane corresponding to the front surface of the strike stratum. A method for filtering across horizontal edges comprises determining which macroblocks are considered to be vertically adjacent to each other. The method also includes forming a first mask layer having a plurality of first openings exposing the fin structures in the first region near the second region; and removing the fin structures in the first region near the second region.
