    Figures & Tables(1)
    Hybrid lattices supporting quasi-BICs: (a) The schematic showing the cancellation of far-radiation field for the symmetry protected BIC structures. (b, c) The Fabricated samples showing the superlattice geometry of the Universal (U)-qBIC and Hybrid (H)-qBIC metastructures. (d) The universal inverse quadratic behaviour of the Q- factor of BIC system with respect to its assymetry paramater. (e) Experimetal THz spectrum showing the improved Q-factor numbers for the H-qBIC resonance compared to the U- qBIC resonance.
