Highly Efficient Broadband Light Absorber Based on Nonuniform Hyperbolic Metamaterial Film

Figure 7

(Color online) (a) magnetic field pattern for the nonuniform metamaterial film of finite thickness nm; (b) the component of Poynting vector, . and components of Poynting vector; and are plotted in the inset for (solid lines) and (dashed lines). Near the resonance point (nm) is tens of times higher than , and the energy flows mainly in the opposite direction. The radiation wavelength is 500 nm.
