Abstract [en]

The main goal of this thesis is to establish a method and estimate the complex material constants for the radial and thickness mode. This has been done in two separate methods. For the thickness mode material constants, a optimization script in MATLAB has been developed, which is capable of directly optimizing all the input parameters for the xTrans, for both active and passive layers. The method has been evaluated, and the complex material constants describe behavior in accordance with measured data. For estimating the radial mode complex material constants, an evaluation a publish method by S.Sherrit has been done.
