Design, theory, and measurement of a polarization insensitive absorber for terahertz imaging
arXiv:0807.3390 · doi:10.1103/PhysRevB.79.125104
Abstract
We present the theory, design, and realization of a polarization-insensitive metamaterial absorber for terahertz frequencies. We derive geometrical-independent conditions for effective medium absorbers in general, and for resonant metamaterials specically. Our fabricated design reaches and absorptivity of 78% at 1.145 Thz
