Ω-particle model. a Current distribution for the lowest frequency resonance at 5.6 GHz in conjugated double-layered gammadion chiral metamaterials. The red (blue) arrows denote the direction of current in the metallic elements in the front (back) layer. The resonance can be understood as a superposition of electrical and magnetic resonances, ER, MR, and ER’. Adapted from Ref. [42]. b Schematic figure of Ω-particle. (left) Magnetisation M is strongly induced by electric field E at electrical resonance (ER). (right) Polarisation P is strongly induced by magnetic fields H at magnetic resonance (MR). q and i are induced electric charge and current respectively
