Abstract

A periodic array of nanoparticles scatters electromagnetic waves in different diffraction orders, and such periodic arrangements of nanoparticles result in significant field enhancements compared to a single nanoparticle. We investigate multipole Mie resonances in MXene antennas, uncovering absorption enhancement, reflection suppression, and phase variation through analytical models, simulations, and experiments. We study lattice resonances of lossy materials, such as transition metals nickel, titanium, and tungsten, as well as metalloid germanium. We study the impact of substrate and superstrate on Rayleigh anomaly dependency, showing that the resonance peak shifts according to the surrounding medium refractive index. Exploiting these resonances can enable metasurfaces for efficient, broad-spectrum light absorption in large-scale sensing, photodetectors, and energy harvesting applications.
