Multispectral broadband PIT and Fano resonance in skewed dipolar metasurface
چکیده انگلیسی
The dipolar charge distribution are most common phenomenon behind the electromagnetic radiating elements and antennas. Plasmonic nanostructures are used to induce nanoscale dipolar resonances when coupled to incident light. It is interesting to investigate the effect of skewness in the conventional dipolar resonances, which is introduced through geometrical effects in nanostructures. Here, S-shaped skewed dipolar nanostructure is used to add skewness to the dipole modes and therefore induce plasmon hybridization effects between bright and dark plasmon modes, leading to multispectral broadband plasmon induced transparency (PIT) and Fano resonances. Additionally, effective group index of the skewed dipole metasurface is retrieved and is found to be very high within the PIT window suggesting its potential use in slow light applications.
