An object is to provide a material suitably used for a semiconductor included in a transistor, a diode, or the like. The magnitudes, polarities, and positions of the magnetic or electric field sources are configured to have desirable correlation properties, which may be in accordance with a code. The polarization filter areas are arranged outside of the transparent area, generally have a concentric ring shape, and include left and right filter areas so that their polarization transmission axis directions define an angle \u03b1. The method involves the carrier reading the identifying information contained in the radio frequency identification tags on each mail piece while each mail piece is in the trays or tubs and removing one or more mail pieces in the tray or tub that are to be routed differently than that routing information contained on the outside of the trays or tubs. The method uses an apparatus with a feed reel from which a rolled tarp may be unwound; a table, across which a said tarp may be drawn; a take-up reel, onto which a the tarp may be rolled; and a grommet setter positioned relative to the table to permit an operator to set grommets on a the tarp as the tarp is drawn across the table.
