Connection between ultrasonic waves and the electrical capacitance for Granite and Plexiglas.

Abstract: This final project contains the results of measurements made to investigate the electrical capacitance changes due to ultrasonic waves. The problem was to find an accurate and precise method to measure the electrical properties. I would like to thank Claes Hedberg and Kristian Haller for their help and support, which have been of outmost importance to all stages in my project work.
