Non-Destructive Evaluation of Materials Using Pulsed Microwave Interrogating Signals and Acoustic Wave Induced Reflections
Abstract
A class of inverse problems is formulated for the estimation of material dielectric parameters using reflections of pulsed microwave interrogating signals from moving acoustic interfaces in the dielectric. A model for acoustic pressure-dependence of material constitutive parameters in Maxwell's equations is presented and analyzed. Theoretical and computational findings for approximation and estimation are given.
