Abstract

Anisotropic black body absorption has been reported in high-density and vertically-oriented carbon nanotube (CNT) forests[1]. Recently, THz wave generation was reported from perpendicularly aligned CNT films placed on substrates[2]. 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.
