Spectral properties of straight hollow core Circular Tube Lattice Fibers in the THz regime are analyzed both numerically and experimentally. Good agreement between simulated and manufactured fibers is found proving that these fibers have high potential for THz applications. Finally, bending properties are investigated with FEM simulations, showing that low-order transmission windows are strongly robust against extra losses due to the bending.
