Abstract
An angular and spectral selective absorber in ultrathin metamaterials is an absorber having an absorption wavelength, λ. Embodiments of the invention include at least one primary layer having a thickness, d, and a relative permittivity of epsilon-near-zero, ε. At least one reflective secondary layer is associated with the primary layer. The association is by bonding.
