Numerical Study of the Optical Response of $\text{ITO}$-${\text{In}_{{2}}{\text O}_{{3}}}$ Core-Shell Nanocrystals for Multispectral Electromagnetic Shielding

Nowadays, materials to protect equipment from unwanted multispectral electromagnetic waves are needed in a broad range of applications including electronics, medical, military and aerospace. However, the shielding currently use bulky work effectively only limited frequency range. Therefore, nanostructured under investigation by relevant scientific community. In this framework, design nanomaterials must be supplemented with proper numerical models that allow dealing non-linearities being effective predicting their absorption spectra. study, response metal-oxide nanocrystals capability has been investigated. A framework was developed predict energy bands electron density profiles core-shell nanocrystal evaluate its optical at different wavelengths. To aim, finite element method software is used solve non-linear Poisson's equation. The simulations allowed model $\mathbf {ITO}$ - {In_{2}O_{3}}$ can applied nanotopologies support an enhanced capabilities.
