Abstract
In scanning acoustic microscopy (SAM), the image quality depends on several factors such as noise level, resolution, and interaction of the waves
with sample boundaries. The theoretical equations for the reflection coefficient and transmission coefficient are suitable for plane boundaries but
fail for curved/rough boundaries. We presented a finite element method-based modeling for the loss coefficients in SAM. A focused and unfocused
lens with a flat object, furthermore a focused lens with a curved object was selected for loss coefficients calculation. The loss calculation in terms of
energy for defining the acoustic reflection and transmission losses and its dependence on the radius of curvature of the test object has also been
presented.
