Using transformation optics a frequency-selective superabsorber can be constructed that consists of an absorbing core material coated with a shell of isotropic double negative metamaterial. For a fixed volume its absorption cross section can be made arbitrarily large at one frequency. The double-negative shell serves to amplify the evanescent tail of the high-order cylindrical waves, which induces strong scattering and absorption. Our conclusion is supported by both analytical Mie theory and numerical finite-element simulation. Interesting applications of such a device are discussed.

  7. There is already a device known as the perfect metamaterial absorber. The SA proposed here is different from the perfect metamaterial absorber. The former is to achieve arbitrarily large absorption efficiency, whereas the latter is to mimic a blackbody. In fact, it is also possible to design an SA such that it behaves as a near ideal blackbody, with a high absorption efficiency and a low scattering efficiency. See N. I. Landy, S. Sajuyigbe, J. J.
