Two-dimensional materials (2Ds) are arguably the forerunners of the greatest modern revolution in materials science given their extraordinary properties compared to bulk materials. This Master's project work plan, which is linked to the Jovem Pesquisador project 2019/14017-9, aims at the numerical modeling of polaritonic properties of a variety of photonic crystals, including hBN and alpha-MoO3 resonators. In particular, the project will address the simulation of nanophotonic structures under more realistic conditions, considering factors such as roughness, morphological deformations, crystalline defects and chemical heterogeneity. Such resonators have great potential for application in nanophotonic circuits for molecular sensing, optical amplitude modulation and offer a physical platform for fundamental studies of light transport in the subdiffractional scale. Such modeling, to be developed with commercial codes (COMSOL Multiphysics + Wave Optics), will support the interpretation of scanning optical microscopy data in the near field (s-SNOM) of resonators and other photonic nanostructures at the IMBUIA station at Sirius/LNLS, whose specialty is the possibility of carrying out infrared and THz synchrotron spectroscopy with a spatial resolution of 25 nm.
