Surface plasmons have optical properties, which are very interesting. For instance, surface plasmons have the unique capacity to confine light at the nanoscale [1–3]. Moreover,surfaceplasmonsareverysensitivetothesurroundingmediumandthepropertiesofthe materialsonwhichtheypropagate.Inadditiontotheabove,thesurfaceplasmonresonancescanbe controlledbyadjustingthesize,shape,periodicity,andmaterialsnature.Indeed,thetechnological progressallowsresearcherstoproducenewplasmonicsystemsbycontrollingalltheparameters describedpreviously[4–14].Moreover,theoretical,computational,andnumericalsimulationtools havebeendevelopedinthislastdecade,allowingforabetterunderstandingoftheopticalproperties of plasmonic systems [1]. Thus, all these optical properties of plasmonic systems can enable a greatnumberofapplications,suchasbiosensors[15–20],opticaldevices[21–24],andphotovoltaic devices[25–28]. 2.Synopsis Thisspecialissueiscomposedoffivereviewarticles,fiveresearcharticles,andtwocommunications.
