A THz plasmonic structure based on metallic wire woven meshes to support Fano resonance is presented in numerical calculation. The structure unit of the woven metal wire is critical to perform this resonance field due to its asymmetry, which is compared with the symmetry of metal-hole-array. Using different bent wires with various curvatures on the woven metal wire structure can modulate the spectral properties of resonance field in the frequency and bandwidth. High Q-factor resonance are thus optimized via the dimensions of the wire bending section and realized to confine a large volume of resonance field.
