Abstract
We discovered a new transmodal Fabry-P\'erot resonance that one elastic-wave mode is maximally transmitted to another when the phase difference of two dissimilar modes through an anisotropic layer is exactly odd multiples of {\pi}. Unlike the well-established Fabry-P\'erot resonance, the transmodal resonance must involve two coupled elastic-wave modes, longitudinal and shear. The formation of wiggly transmodal transmission spectra is due to structural instability appearing in anisotropic mode-coupled elastic-media. Experiments with elastic metamaterials confirmed our findings which can play a critical role in shear-mode ultrasound applications.
