The dependence of transmission/absorption of terahertz (THz) radiation on strain in graphene is investigated experimentally and with the aid of ab initio calculations. By applying strain to chosen graphene layer(s), the effective sheet conductance can be fine-tuned to necessary value to design tunable passive THz components (such as shields, filters, polarizers, etc.) utilizing the high absorption ability of graphene. The positive influence of non-perfectness of chemically vapor deposited (CVD) graphene for strong tunability versus mechanical deformations is also discussed.
