| الوصف: | Hyperbolic metamaterial (HMM) based absorber comprising metasurface having periodically arranged hafnium nitride nanodisks was investigated. The constitutive and absorption properties of the structure were evaluated considering different parametric and operational conditions. Both the TE- and TM-incidence waves were studied along with different incidence and polarization angles. Using the finite integration technique, the absorber was found to exhibit high (polarization insensitive) ultrawideband absorption. With such features, the proposed HMM has prospects in developing plasmonic devices to enhance solar cell efficiency and other optical applications. |
