Asymmetric tip design for far infrared metamaterial sensor
摘要
Abstract
This study investigates an asymmetric tip design for a far-infrared metamaterial aimed at enhancing the Q factor and detection sensitivity.Employing the conventional double-split square ring resonator as a model,we conducted theoretical simulations to investigate the impact of different tip angles on the electric field distribution,resonance spectrum,and Q factor.The results show that the asymmetric tip increases the surface electric field of the resonator,decreases the full width at half maximum(FWHM)of the resonance peak,and increases the Q fac-tor to over three times that of the conventional split ring.Our findings offer valuable insights for the development of highly sensitive far-infrared metamaterial sensors.Furthermore,we propose a straightforward and practical op-timization approach to enhance the Q factor of conventional split ring metamaterials.关键词
