Phononic Crystal Waveguide Transducers for Nonlinear Elastic Wave Sensing
Second harmonic generation is one of the most sensitive and reliable nonlinear elastic signatures for micro-damage assessment. However, its detection requires powerful amplification systems generating fictitious harmonics that are difficult to discern from pure nonlinear elastic effects. Current sta...
