Extreme Frequency Conversion from Soliton Resonant Interactions

We present a metastructure architecture with bistable microstructure that enables extreme broadband frequency conversion. use numerical and experimental tools to unveil the relationship between input excitations at unit cell level output responses macrostructural level. identify soliton-lattice mode resonances resulting in input-independent energy transfer into desired metabeam vibration modes as long transition waves are triggered within metastructure. observe both low-to-high high-to-low incommensurate interactions metabeams, thus enabling exchange bands 2 orders of magnitude apart. This behavior generalizes fluxon-cavity resonance superconducting electronics, providing general method conversion mechanics. Importantly, introduced allows for expanding metamaterials design paradigm by fundamentally breaking dependence macroscopic dynamics on properties. The nature implies potential applications regulation transduction.
