Toward Filtering Aspects of Silver Nanowire-Based Hyperbolic Metamaterial

the theme of paper is pivoted to the spectral characteristics of silver nanowire hyperbolic metamaterial (nwhmm)-based filter. the light waves were allowed to fall upon the nwhmm surface comprised of periodic arrangement of the array of sub-wavelength-sized silver nanowires of circular cross-section immersed in silicon dioxide (sio2) medium; the sio2 layer being fabricated over silicon (si) substrate. the reflection spectra were extracted in the 400–1400 nm wavelength range corresponding to different operational conditions. it was observed that the reflectance characteristics greatly depend upon the angle of incidence, diameter of silver nanowires, and nwhmm layer thickness. certain operational conditions exhibit the structure to be useful for wideband filtering applications.
