Waveguide A waveguide for carrying waves by inductive coupling comprises a plurality of resonant5 elements, the plurality of resonant elements including a first resonant element; a second resonant element; and a coupling section capacitively coupling the first and second resonant elements, wherein the coupling between the first and second elements produces a first pass-band and a second-pass band, different from the first pass-band, the first pass-band being associated with the resonance of the resonant elements and the second pass-band being10 associated with resonance of the coupling section. |
