Highly Sensitive Thin‐Film Sensing with a Toroidal Dipole Resonance in the Midinfrared Supported by an E‐Shaped Germanium Metasurface
Optical sensing applications based on resonant structures always demand on novel optical resonances with large quality factors to achieve high sensitivities. Herein, it is experimentally demonstrated that a toroidal dipole (TD) response working in the midinfrared, supported by a metasurface structur...
