Abstract: Investigation of nanoparticles independent of the incident wave polarization and its effects on Fano resonance is noticed in this article. In various studies, achievements of Fano resonance have been noticed in both symmetric and asymmetric structures based on interaction between bright and dark mode. However, Fano resonance in symmetric particles is limited to some special shapes therefore, we have noticed the existence of Fano resonance in asymmetric U-I structures. On the other hand, for making independent the polarization and reducing the polarization effect on cross section, we have suggested special array of the particles. The results show that we have both dark and bright modes at the bonding resonance and both array models show the polarization independence to the incident wave for mid infrared applications. For bio-sensing applications, the FOM factor is studied and compared for each resonance and it is revealed that at the Fano resonance, the FOM factor shows highest value in comparison to plasmonic mode at U-array structures which makes the Fano resonances valuable for distinguishing materials in the optical regime with more resolution.
