Abstract

Embodiments of the present invention provide a resonant assembly (105, 305, 405, 700, 750, 930), comprising first and second resonant members (110, 410), the first and second resonant members each being configured to resonate at a respective different resonant frequency when excited by an electromagnetic field, wherein at least one resonant member comprises a discontinuous loop (112, 710, 760) having at least one capacitive element (114, 720, 721, 722, 770, 771, 772) connected between free-ends of the loop.
