“…Then from Eqs. ( 18 )–( 22 ) we find: where is the frequency of dipolar resonance of a single metallic nanowire surrounded by a dielectric medium 43 . Note that for type-I HMM we should have and ( means real part) and the imaginary parts of them must be small enough to be negligible.…”

We present the theory of electromagnetic energy propagation through a dispersive and absorbing hyperbolic metamaterial (HMM). In this way, the permittivity tensor components of HMM (especially, nanowire HMM) may appear to be hopeless, but as a non-trivial step, we find that they can be cast into more transparent forms. We find under the influence of an electromagnetic wave, the responses of nanowire HMM (multilayer HMM) in the directions perpendicular to and parallel to the optical axis are similar to those of Lorentz (Drude) and Drude (Lorentz) media, respectively. We obtain simple expressions for the electromagnetic energy density formula of both typical structures of HMMs, i.e., nanowire and multilayer HMMs. Numerical examples reveal the general characteristics of the direction-dependent energy storage capacity of both nanowire and multilayer HMMs. The results of this study may shed more physical insight into the optical characteristics of HMMs.

“…The HMMs 17 – 21 , which form a subclass of metamaterials, has attracted the attention of many authors. More recently, we have used the electrostatic theory to study the propagation of electrostatic waves in unbounded 22 and bounded 23 – 25 media of nanowire-based HMMs. A HMM exhibits a unique property of having anisotropy with simultaneously different signs of the permittivity tensor components, i.e, and 19 , 20 .…”

The electrostatic (or, in a better word, quasi-electrostatic) theory of waves propagation in a long, rectangular waveguide having perfect electric conductor walls that filled with an anisotropic medium (here, a medium of nanowire-based hyperbolic metamaterials) is presented. Some data on characteristics of these waves are prepared. The presented results include electrostatic field configurations (modes) that can be supported by such structures and their corresponding cutoff frequencies, group velocities, power flows and storage energies.
