Anisotropic black body absorption has been reported in high-density and vertically-oriented carbon nanotube (CNT) forests. Recently, THz wave generation was reported from perpendicularly aligned CNT films placed on substrates. Unique optical properties of CNT forests opened the next door of opt-electronics applications. Size and shape controlled CNTs is a candidate of metamaterial nano-rod antenna in THz to the visible range. In this paper, we report anisotropic optical properties of vertically aligned CNT forests with/without SRR (Split ring resonator) patterning in IR and THz regions.
