Keywords:surface plasmon, plasmonic crystal, vortex

Control of surface plasmon resonance is a key technology in photonics in the future. We found an intriguing plasmonic eigenstate which induces vortex-like energy flow in a plasmonic crystal without space inversion symmetry This effect is referred as a plasmonic tornado state. In our presentation, we discuss the characteristics of the plasmonic tornado state in detail.
