“…3(a), demonstrating three regimes with different level of robustness to the position disorder. The values of ε for achieving strong robustness is ameliorated to a smaller value around 15 due to the optimal lattice [47]. The typical transmission spectra for both PhC and MM regimes can be found in Supplementary Materials.…”

“…We recall that metasurfaces consist of resonant structural elements, which are responsible for the unusual properties of these structures. Unlike the photonic crystal membranes, the metasurfaces require a large number of plane waves to reproduce a multipole resonance in the structural element correctly, which correspond to almost flat dispersion‐less branch at the Γ point …”

This approach became essential for constructing negative index media, which laid a strong foundation for the burgeoning field of metamaterial photonics. Split-ring resonators as the basic building blocks of metamaterials were first proposed to be made up of metallic inclusions at the microwave frequencies. [9] However, beyond the microwave frequencies, metals show considerable Ohmic loss, which created the need for all-dielectric resonator platform with the promise to offer low-loss meta-optics and photonics. The last few years have witnessed an unprecedented use of dielectrics in optical metamaterials based on high-index dielectric materials that have strongly emerged as an alternative approach to disrupt the lossy metalbased subwavelength photonics. [10][11][12][13][14][15][16][17][18] Several interesting phenomena of metamaterials are driven by strong resonances, and their quality (Q) factors become an extremely important parameter that determines the strength of light-matter interaction. The structures with high Q factors offer a new route for strong localization of electromagnetic energy in near fields that allow ultrasensitive sensors and other optical devices. [19][20][21][22][23] Recent trends in this field are based on so-called bound statesThe authors declare no conflict of interest.

Modern nanotechnology provides tools for realizing unique photonic structures with the feature size comparable or even smaller than the wavelength of light. However, the fabrication imperfections at the nanoscale inevitably introduce disorder that affects or even destroys many functionalities of subwavelength photonic devices. Here we suggest a novel concept to achieve a robust bandgap which can endure disorder beyond 30% as a result of the transition from photonic crystals to Mie-resonant metamaterials. We demonstrate photonic waveguides and cavities with strong robustness to position disorder. Utilizing Mie-resonant metamaterials with high refractive index provides an alternative approach to the bandgap-based nanophotonic devices instead of harnessing the fabrication precision, and also brings new functionalities.
