摘要: In this study, a novel design of porous octagonal photonic crystal fibre with metal-coated central hole is investigated and analysed in the terahertz (THz) range. The suggested structure near frequency 1.0 THz by using full vectorial finite difference method. effects geometrical parameters bending radius on mode effective index, area attenuation proposed are investigated. numerical results reveal that smaller than core without 80%. addition, very low can be obtained because porosity inside region.
