The field of plasmonics is capable of enabling interesting applications in different
wavelength ranges, spanning from the ultraviolet up to the infrared. The choice of plasmonic …

Disordered metallic nanostructures have features that are not realized in well‐defined
nanometallic counterparts, such as broadband light localization and inhomogeneous …

Nanoporous metallic networks are endowed with the distinctive optical properties of strong
field enhancement and spatial localization, raising the necessity to map the optical …

We investigated the formation of nanoporous metallic networks through a physical vapor
deposition (PVD) process. Utilizing transmission electron microscopy (TEM), we observe the …

Metamaterials and plasmonic structures made from aluminum (Al) have attracted significant
interest due to their low cost, long-term stability, and the relative abundance of aluminum …

Herein, centrosymmetric aluminum plasmonic structures composed of triangular cavities are
studied and their long‐range coupling by cathodoluminescence nanoscopy are visualized …

Since the pioneering set of aerogels created by Kistler in 1931, this fascinating class of
materials has evoked a myriad of scientific and technological possibilities and inspired an …

En esta tesis, investigamos fenómenos que involucran el mezclado de tres ondas como
generación de segundo armónico (GSA), de suma de frecuencias (GSF) y de diferencia de …
