Abstract
A method for calculating the change in percent voids between a reference location and a second location in a medium. The method includes obtaining a reference reflection coefficient of an electromagnetic wave reflection at the reference location, and a second reflection coefficient of an electromagnetic wave reflection at the second location. The obtained reflection coefficients are used to calculate a percent change in reflection coefficient. A reflection conversion factor correlating the change in the reflection coefficient to a change in percent voids in the medium is calculated and is used to calculate a change in percent voids between the reference and second locations based on the calculated percent change in reflection coefficients.
