Keywords:Nano-structured mediums, Scattering characteristics, Complex mediums
The scattering of waves remains greatly important phenomenon of research focus involving the objects having size parameters ranging from macro- to nano-structured dimensions. Among the others, some of the notable examples would include the radar- and antenna-related applications. Electromagnetic cloaking is greatly dependent on the extent of scattering response. The role of scattering has been discussed in the context of metamaterials comprised of metal-dielectric partners crafted in certain forms. Surface plasmon resonance remains the prime feature as the effects can be tailored depending on the shape and size of meta-atoms. VO2 being a phase-changing material, here we discuss the scattering characteristics of SiO2-VO2 nanoshells considering different core/shell dimensional parameters, and also, the ambient temperature. It has been found that the scattering cross-section greatly depends on the operating temperature as well as nanoshell dimensions. Also, the nanoshells can be designed to exhibit very low scattering in certain regions of electromagnetic spectrum.
