Abstract

A wrapper for a terahertz wave according to an embodiment of the present invention includes: a terahertz wave transmission layer that is made of a material that transmits a terahertz wave; and an electric field enhancement structure that enhances an electric field by reacting with a predetermined frequency band of terahertz waves passing through the terahertz wave transmission layer. An optical identification device for a terahertz wave according to an embodiment of the present invention includes m identification units composed of: a terahertz wave transmission layer that is made of a material that transmits a terahertz wave; and a waveguide grating that resonates at a natural resonant frequency when receiving the transmitted terahertz wave, in which the natural resonant frequency is any one of a first natural resonant frequency to an n-th natural resonant frequency.
