Abstract
This study focuses on inverting the geometrical characteristics of the surface of corrugated interfaces from ultrasonic polar scan data. Based on an analytical model to predict the reflection and transmission of homogeneous plane waves on a 2D periodically corrugated surface, and in combination with numerical calculations and machine learning, we were able to inversely estimate the corrugation parameters (the periodicity, shape and height) from the reflected ultrasonic polar scan landscape.
