Second Harmonic Modulation for Ultrasonic Signals Based on the Design of the Phononic Crystal Filter
Nonlinear ultrasonic non-destructive testing (NDT) is a widely used method for detecting micro-damages in various materials and structures due to its high sensitivity and directional capability. However, the extraction and modulation of extremely weak nonlinear ultrasonic signals is quite a challeng...
