Abstract
Acoustic particle metamaterials in Smart Proppants reflect sound waves at distinct frequency ranges when receiving sounds from an above ground or in-ground source. Sound receivers at separated locations receive the reflected sound waves at distinct times, providing information on location of the Smart Proppants, which are mixed with conventional proppants. The Smart Proppants prevent transmission of waves at precise ranges of frequencies and reflect those waves.
