Metaphotonics with subwavelength dielectric resonators

Abstract: The recently emerged Mie resonant metaphotonics (or Mietronics) provides novel opportunities for subwavelength optics. Mietronics employs resonances in isolated nanoparticles and structured surfaces. We present a brief summary of the key concepts underpinning this rapidly developing area of research, using the examples of isolated high-index dielectric subwavelength particles. We also discuss recent advances and future trends in designs of high-Q elements for efficient resonant spatial and temporal control of light.
