Broadband generation of quasi bound-state-in-continuum modes using subwavelength truncated cone resonators

Chun-Ho Lee, Mohamad Reza Nurrahman, Dongha Kim +3

Allowing a high quality factor (Q-factor) to a sub-wavelength dielectric resonator, quasi-bound states in the continuum (Q-BIC) has gained much interest. However, the Q-BIC resonan…
