Defense Intelligence Reference Document High-Frequency Gravitational Wave Communications

Defense Intelligence Agency · 57 pages · text from the file's own layer

This Defense Intelligence Reference Document was prepared by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) program, is dated 6 April 2010 and is part of a series of advanced technology reports produced in FY 2009. It reviews proposed laboratory generators and detectors of high-frequency gravitational waves for communications. It favors an infrared-excited molecules transmitter and the Li-Baker detector, estimating about 1.9 million bits per second over 7,000 km through the Earth. It also discusses timing standards and interplanetary navigation uses.

The stack of orbital planes are no replaced by a stack of N plates each containing n
molecules in each waveguide ring as exhibited in Figure 6. Now there is a HFGW wave
moving up the axis of the rings (or normal to the waveguide plates) and increasing in
strength according to the product nN2.

One should consider the IR rings in more detail. As calculated, the IR wavelength is
about 2.Sxl0 6 m. The IR waveguide has a cross-sectional area radius of )./4 in order
for it to be a monomode (lowest order mode) so that the phase doesn't change across
the waveguide. Thus the cross-sectional area of each IR ring is rr x (2.Sxl0-6 m/4) 2 =
1.23x 10-12 m 2 and its diameter is 1.25x10-6 m. The volume of each 100-m radius nano-
size toroidal ring is 2n x (100) x (1.23x10- 12
) = 7.7x10- 12
m 3
. The mass density of
pentane is divided by its molecular mass and that gives the density of jerkable masses
of 6.3x10 28 m- 3 . Thus the number of jerkable mass pairs, n, in a 100 m radius circular
wave guide 2n = (6.3x1028 ) x ( 7.7x10· 12 ) = 4.8Sxl0 17 submicroscopic "particles" or
potentially jerkable masses or n = 2.45x 10 17 mass pairs. According to Table 1 of
Woods and Baker (2009) for pentane Pi= 4.62x 10-16 W. Thus the flux at one meter
distance for all of the mass pairs in a single ring from Equation (8) of Black and Baker
(2009) is n x (0.01146) x P, = 1.29 wm- 2 . It should be recognized that the axes of the
opposite pentane molecules jerk (in response to the EM wave) may not be anti-parallel
and tangential to the circular waveguides. On the other hand, the radiation pattern for
the HFGW exhibits some omni-directional form, as shown in Figure 7, so significant
HFGW radiation will be directed along the axis of the stack of circular waveguides
(normal to the plates) and the HFGW will build up.
