N2 - In this communication, an all-metallic epsilon-near-zero graded-index lens is demonstrated working at terahertz (THz) frequencies. The lens is designed using an array of narrow hollow rectangular waveguides working near cut-off of their fundamental mode emulating an epsilon-near-zero medium. The prototype is evaluated both experimentally and numerically demonstrating a good agreement between them with a focal length of 6 mm at the frequency of 0.675 THz. An experimental power enhancement at the focal length of 42 times is achieved compared to the case without the lens.
