Metamaterials are designed materials with metal-dielectric or all-dielectric sub-wavelength features that help realize novel material properties. While the metal-dielectric structures make use of surface plasmon polariton modes, all-dielectric structures could be lossless. For light-matter interaction studies for basic science as well as for various applications, it would be interesting to realize suitable structures. Dispersionless metamaterials have unique applications. A plasmonic quasicrystal structure with a broadband, launch angle, and polarization-independent response shows enhanced transmission, second harmonic generation, and magneto-optical effects in multiple bands. In addition, it would be interesting to see its use in plasmon-mediated exciton-exciton long-range interaction, and label-free sensing of biomolecules, among others. Some of the other metamaterials like optical reflectionless potential, perfect absorber, hyperbolic metamaterial, bound state in continuum structure will be presented along with their applications in anti-reflection coating, single photon emitters, and reusable biosensor.
