Abstract
Fano resonances are produced by integrating an electric split ring resonator (eSRR) and an I shaped resonator (ISR) into a composite metasurface. By adjusting the length of the ISR the degree of asymmetry in the line shape can be controlled and even made to be symmetric. Metasurfaces of the composite structures are fabricated, and their transmission is measured with terahertz time-domain spectroscopy. The measurements show good agreement with finite difference time domain (FDTD) simulations. © 2019 IEEE.
