Plasmonic metamaterials (MMs) have enabled their novel applications across numerous engineering fields ranging from photodetecting to bio-imaging, cancer diagnosis, and photovoltaics. However, as a vast majority of reported plasmonic MMs are based on materials with relatively low melting point such Au or Ag, utilities limited for lower-temperature applications. Thus, realizing resonance refract...

This work reportson plasmonic effects (i.e light scattering and absorption properties) induced by two different gold nanoparticles (AuNPs)-shaped: spherical particle triangular particle. The cross-section electric field profiles have been investigated using theboundary element method (MNPBEM toolbox). Two configurations: the isolated AuNPand coupledtwo-gold NPsystem considered to evaluate local...
