Non-radiative optical modes attracted enormous attention in optics due to strong light confinement and giant Q-factor at its spectral position.The destructive interference of multipoles leads to zero net-radiation and strong field trapping.Such radiationless states disappear in the far-field,localize enhanced near-field and can be excited in nano-structures.On the other hand,the optical modes turn out to be completely confined due to no losses at discrete point in the radiation continuum,such states result in infinite Q-factor and lifetime.The radiationless states provide a suitable platform for enhanced light matter interaction,lasing,and boost nonlinear processes at the state regime.These modes are widely investigated in different material configurations for various applications in both linear and nonlinear metasurfaces which are briefly discussed in this review.
