Introduction: In the 1950s, I co-authored a paper on gravitational dynamics entitled “Satellite Librations”. I had just received my Ph.D. at UCLA in Engineering with specialization in Astronomy (UCLA termed it an “Aerospace” degree) and I was appointed to the faculty of the Astronomy Department and later the Engineering Department as Lecturer and Assistant Professor.

In the 1960s, I became the Head of a Lockheed laboratory and a Dr. Robert Forward contacted me regarding my Satellite Librations paper. He was interested in something called “gravitational waves” and his Ph.D. thesis was the design of a resonance device developed by a Joseph Weber called the “Weber Bar”. I invited Dr. Forward to deliver a lecture to my staff and was intrigued with the possibility of sensing low-frequency (LF) gravitational waves (GW) with frequencies on the order of a kHz or less using the Weber Bar.

I was also intrigued by the possibility of generating high-frequency (HF) gravitational waves (GW) exhibiting frequencies of a GHz or more. At the time, however, I saw no practical means to generate the HFGW. Recently, my interest in HFGW has been rekindled and I presented a paper on the subject in 2000 to the American Institute of Aeronautics and Astronautics or AIAA...

From the 1960s through the 1980s there was considerable skepticism concerning the existence of gravitational waves and consequently little attention was paid to the literature concerning the laboratory generation of GW. However, the experimental references I've listed below should provide ample evidence that the laboratory generation and detection of high-frequency gravitational waves has been thoroughly studied by dozens of scientists and many of the devices suggested are both feasible and practical if we take advantage of recently developed technology.
