Graded index ε-near-zero (GRIN-ENZ) quasi-optical components such as beam steerers and power splitters are designed, simulated and analyzed. The GRIN-ENZ medium is realized using stacked narrow hollow waveguides whose infinite array shows the first transmission peak at 1.0002 THz. Several GRIN-ENZ beam steerers to channel a normal incident plane wave to different output angles (15, 45, 65 and 80°) with good impedance matching (low reflection) are analytically and numerically demonstrated using planar structures with a thickness of 5λ0=1500 μm along the z-axis. Moreover, symmetrical and asymmetrical power splitters are designed with output angles (±45°) and (-80, +35°), respectively.
