Gravitational Wave Generation and Detection Using Acoustic Resonators and Coupled Resonance Chambers

An experiment is described for the generation and detection of High‐Frequency Gravitational Waves (HFGWs) in the laboratory utilizing acoustic piezoelectric resonators for generation, and coupled resonance chambers for detection. Film Bulk Acoustic Resonators or FBARs (similar to those utilized in commercial cellular telephones) energized by magnetrons (similar to those utilized in microwave ovens) are distributed in a ring‐shaped array several hundred meters in diameter. The magnetrons are phase locked and are sufficient in number to energize millions of FBARs fabricated on thousands of wafers. The FBARs produce jerks (time rate of change of acceleration or a third time derivative motion imparted to their electrode masses) at a frequency of 2.45GHz. The resulting 4.9GHz HFGW is focused at the center of a segmented or asymmetrical ring of FBARs and is concentrated there by a high‐temperature superconductor (HTSC) to generate a HFGW flux on the order of 17mW m−2 to 7W m−2.
