Specifically, metasurface unit cells with broken in-plane symmetry have unlocked precise control over the linewidth and therefore the quality factor (Q factor) of BIC-based resonances [1]. Combined with tunability over a wide frequency range, this approach has opened up a broad spectrum of applications from biochemical sensing [2] to higher harmonic generation [3].enQ-factorFabricationResonant frequencyEuropeMetasurfacesFrequency conversionSensorsTechnology::600: TechnologyConference Paper10.1109/CLEO/Europe-EQEC52157.2021.9542668
