Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Advanced Photonics Research, EarlyView.Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.
