High Q-Factor Resonance in a Symmetric Array of All-Dielectric Bars

High Q-Factor Resonance in a Symmetric Array of All-Dielectric Bars

Strong electrical dipole resonance (ER) with high quality-factor (Q) (over several thousands) in a simple silicon all-dielectric rod arrays without asymmetric structure is achieved in the near infrared (NIR) wavelength range. According to numerical simulations, strong high order ER is excited by ver...
