Representation of the SAM setup, which includes a signal generator, RF amplifier (\(T_x\)), and signal receiver amplifier (\(R_x\)) to excite and detect ultrasonic signals. The system is integrated with an XY stage and Z-axis motor controller for precise spatial positioning of the transducer. Automated scanning and data acquisition are managed by a computer-based control unit linked to the trigger and stage controllers. The sample is positioned in a dedicated container to allow controlled ultrasonic wave propagation55,56,57.
