Light manifests as an electromagnetic wave resulting from the reciprocal interaction of time-varying electric and magnetic fields. The characteristics of these waves are contingent upon the type and composition of the medium through which they propagate. Metaphotonics explores novel optical behaviors that transcend conventional optical properties by establishing a new domain using diverse artificial nanostructures.
The prefix "Meta," derived from Greek, signifies "beyond" in the context of metaphotonics, denoting artificial attributes not naturally occurring. The integration of these artificial structures can lead to the emergence of unexpected and advantageous phenomena that differ from those observed in naturally existing materials. By offering control over various optical properties, including amplitude, phase, polarization, and wavelength at a sub-wavelength scale, metaphotonics holds potential applications in diverse fields such as sensors, displays, communication, energy, and biotechnology.
