“…Note that it is not necessary to have the FBAR tracks perfectly aligned (that is the FBARs exactly across from each other) since it is only necessary that the energizing wave front (from Magnetrons in the case of the FBARs as in Baker, Woods and Li (2006)) reaches a couple of nearly opposite FBARs at the same time. The HFGW beam is very narrow, usually less than 10 -4 radians (Baker and Black, 2009) and increasing N narrows the beam. Additionally multiple HFGW carrier frequencies can be used, so the signal is very difficult to intercept by terrorists, and is therefore useful as a low-probability-of-intercept (LPI) signal, even with widespread adoption of the technology.…”

“…To allow for margins we will take the FBAR dimensions overall as 110x110x2 μm 3 . Let n FBARs be spread out radially like a vane in a double-helix configuration (Figure 3 of Baker and Black, 2009). Thus Δf = 2n N. If n = 1000, then the radial extent of the FBARs vane would be 11 cm.…”

“…We will "stack" these 110 μ thick levels one on top of the other in a double helix configuration (Baker and Black, 2009) in order to increase N and narrow the beam. There will be 10m/110 μm = 9.1x10 4 levels so that N = 2.9x10…”

Some of the statements in the abstract are self-contradictory; it is stated that because of "their ability to pass through all material without attenuation, HFGWs could be utilized for uninterruptible, very lowprobability-of-intercept (LPI), high-bandwidth communications" which is clearly contradictory since the HFGWs must interact with a receiver to be useful.I attempted to clarify this in the attached manuscript as follows:"Although HFGWs do not interact with and are not absorbed by ordinary matter, their presence can be detected by their distortion of spacetime as measured for low-frequency gravitational waves by the Laser Interferometer Gravitational Observatory or LIGO (Abbott, et al., 2008), Virgo (Ballardio, et al, 2001), GEO600 (Hogan, 2008) and for HFGWs by detection photons generated from electromagnetic beams having the same frequency, direction and phase as the HFGWs in a superimposed magnetic field, the LiBaker HFGW Detector (Baker, Stephenson and Li, 2008;Li et al., 2008;Li et al. 2009), by the change in polarization they produce in a microwave-guide loop as in the Birmingham University Detector (Cruise and Ingley, 2005) and by other such HFGW detection instruments (Chincarini and Gemme, 2003;Nishizawa et al. 2008). None of these effects utilized for detection represent interaction with matter in a way that causes GW absorption, but rather interaction with fields and the detection devices do not attenuate the GWs." The detection instruments measure change in GW polarization, distortion of the fabric of spacetime, change in EM that has the same frequency, phase and direction as the GWs, etc. -none of which attenuates the GW.Also, I believe HFGW propulsion is certainly very unlikely, and surveillance also is a non starter if one believes the very small cross-section for interaction with ordinary matter.Too many concepts in the history of Science have been ruled out prior to actual experiments. Conventional propulsion applications of GW have been discussed theoretically by Bonnor and Piper and by Davis and from an astrophysical viewpoint by Bekenstein. The most compelling discussion is found in Landau and Lifshitz where they note qualitatively the possibly significant influence of high-frequency gravitational waves on otherwise static gravitational fields --certainly a possibility that calls for experimental study. Surveillance applications would depend upon the so-far unknown influence of intervening matter between the HFGW generator and detector in a laboratory experiment (no absorption though) and represents a motivation for such an experiment as stated in the manuscript. The following quotes from the manuscript amplify this idea: "These important potential HFGW applications are motivations for HFGW research and development and such an R&D program is recommended for immediate initiation." "The plausibility of the theoretical applications cannot, however, be adequately determined until after a proof-of-concept test is successfully completed." "A quantitative analysis must necessarily await a laborat...

An analysis is accomplished of the input power requirement of High-Frequency Gravitational Wave (HFGW) generators. Several techniques are explored using both off-the-shelf and advancednanotechnology generator elements. It is concluded that proof-of-concept test, involving N off-the-shelf array elements could be of meter to kilometer length and require 25 MW or less power if array elements are in a staggered arrangement. The power and size of an operational nanotechnology HFGW generator or transmitter device can be greatly reduced by the focusing effect of N 2 radiator pairs. Utilization of conventional piezoelectric Film Bulk Acoustic Resonators (FBARs), tailored and scaled for HFGW generation, could provide the initial commercial generation means. The use of the new infrared-energized ring concept of Woods and the use of a double helix array proposed by Baker may even further reduce the power and size requirements of the device to <<20 W and mm in length and width.
