Abstract: The dipole-resonator resistive absorber is a metamaterial absorber operating in the microwave regime. A single unit of the dipole-resonator resistive absorber includes a first rectangular conductive ring having a pair of first resistors mounted thereon and in electrical communication therewith, and a plurality of parallel linear arrays of second rectangular conductive rings, where each of the second rectangular conductive rings has a pair of second resistors mounted thereon and in electrical communication therewith. The first rectangular conductive ring is mounted above the plurality of parallel linear arrays of the second rectangular conductive rings, and this structure is backed by an electrically conductive layer. The single unit dipole-resonator resistive absorber may be expanded into an arrayed structure, forming a polarization-independent dipole-resonator resistive absorber.
