Paper Abstract

We present analytical and numerical analysis of cylindrical hyperbolic metamaterials (CHMM) for realizing superscattering in the visible region. We show that up-to two-fold enhancement in optical scattering can be achieved for the structures with CHMM, when compared to the homogeneous structures of normal materials. Through numerical calculations, it is demonstrated that whispering gallery like resonance is supported at the superscattering condition. We also employ effective medium approximation models for a comprehensive analysis of mechanism behind the superscattering and whispering gallery mode.
