We report some of our recent developments on flat plates or metasurfaces to structure the visible light in an altemative fashion.In this context,the followi
With the help of plasmonic resonance in metallic nanostructures,light absorption at visible and near infrared regime can be significantly enhanced.Such stro
Surface plasmon polaritons (SPPs) carry information or energy that can be localized around or transported among nanoscale metallic structures without suffer
