Microstructures in Polymer Fibres for Optical Fibres, THz Waveguides, and Fibre-Based Metamaterials

Figure 12

Magnetic resonator fibres containing indium metal. (a) A split ring resonator fibre with PMMA in the inner part of the indium resonator and PC on the outer. (b) A layered array of such fibres consolidated in Zeonex slabs. (c) A double split ring resonator fibre. (d) The transmittance of arrays as in (b) consisting of 1, 2, or 3 layers, characterised by the magnetic field of the radiation parallel to the fibre axis. The magnetic resonance is indicated by the drop in transmittance at 0.3 THz. Adapted from (a), (b), and (d) [76] and (c) [77].
