摘要

The substance has an array of conductive wires positioned relative to one another to present negative permittivity relative to electromagnetic waves that have electrical field parallel to greatest dimension of the wires. The waves are propagated at frequency below electrical plasma frequency of the substance that is made of an antiferromagnetic material. Each wire has strips (20, 22) made of conductive ferromagnetic and dielectric materials, where each wire extends along the dimension in a plane of the strips and has thickness twice as small as skin thickness of the ferromagnetic material. The ferromagnetic material is an alloy of iron or cobalt or nickel. The antiferromagnetic material is an alloy of manganese and nickel, iridium or iron or nickel oxide. Independent claims are also included for the following: (1) an electromagnetic waveguide device comprising a left-handed substance (2) an electromagnetic sender or receiver antenna comprising the left-handed substance (3) a method for manufacturing the left-handed substance.
