Nanostructured plasmonic configurations possess resonant optical excitation of desired modes at, and around the interfaces of these structures. These resonant phenomena lead to enhanced electromagnetic fields by several orders of magnitude, thereby leading to intriguing vast range of applications.
In my talk, starting from the basics of plasmons, sensing principles and parameters, we would discuss the recent developments on plasmonic sensors and absorbers. The talk will span topics from surface plasmon resonance/surface enhanced fluorescence/extra-ordinary transmission and their applications.
