Design, theory, and measurement of a polarization-insensitive absorber for terahertz imaging
Published
Journal Article
We present the theory, design, and realization of a polarization- insensitive metamaterial absorber for terahertz frequencies. Effective-medium theory is used to describe the absorptive properties of the metamaterial in terms of optical constants-a description that has been thus far lacking. From our theoretical approach, we construct a device that yields over 95% absorption in simulation. Our fabricated design consists of a planar single unit-cell layer of metamaterial and reaches an absorptivity of 77% at 1.145 THz. © 2009 The American Physical Society.
