Presented to the International HFGW Working Group
by Gary Stephenson

This 2003 Boeing presentation on High-Frequency Gravity Waves provides a concise overview of the current trends, theoretical foundations, and likely successful applications for future gravity-modification technologies based on the generation & detection of High-Frequency Gravitational Waves.

This document was assembled & presented by Boeing employee Gary Stephenson at the 2003 Mitre High-Frequency Gravitational-Wave conference in McLean, Virginia. It is a summary of contemporary research into the direct manipulation of gravitational-force through the generation of gravitational-waves, and features overview-level information on several of the leading concepts to turn electrical energy into directed gravitational-force.

In addition to background information on the role of Einstein's General-Relativity Equation as the foundation supporting the notion of gravitational-waves as a part of natural science, this presentation also shows the concepts behind the notion that increasing the frequency of the gravitational-waves can serve as an effective means of making them more useable for propulsion, communications, and other applied engineering concepts. Further, this presentation features an overview of popular concepts related to HFGW generation, including:

Synchronized Mini Piezo-ElectricTransducers (Romero & Dehnen): A PZT array can be used to create mechanical displacements in a quadrupole pattern to create gravitational waves.

Dielectric Sphere Generator (Portilla & Lapiedra): Gertsenshtein Effect efficiency is improved with an inhomogeneous dielectric.

High-Temperature Superconducting GASER (Fontana): Stimulated emission of gravitons is achieved by coherent gravitational quadrupolar quantum transitions.

HTSC with Polarized EM for GR frame dragging (Chaio): Type II Superconductors convert conditioned EM to GR frame dragging by virtue of their natural impedance matching properties.

Nanotechnology Electro-Mechanical Generation (Baker): Nanotechnology arrays of actuated charges or magnets can be used as a source of  gravitational wave emission.

Electromagnetically-Pumped Toroidal Generator (Grishchuk & Sazhin): An EM resonator in the form of a torus in which an alternating EM field is excited can be used as a source of  gravitational wave emission.

Circular Waveguide Sensor Concept (Ingley & Cruise): A waveguide ring containing a polarized EM wave will experience a polarization change when gravitational waves of the same wavelength pass through the waveguide ring.

Coupled EM Cavities Sensor Concept (Bernard, Gemme, et.al.): A gravitational wave incident on a pair of tuned resonant cavities will cause those cavities to alter their resonant behavior.

Static Magnetic Field with EM Sense Beam Sensor Concept (F-Y Li, et. al.): A gravitational wave in a static B field will have a resonant response to a half frequency photon beam, creating new photon frequency outputs.

GW propagation verses SATCOM for Satellite Communications: Using gravitational waves, one ground station could theoretically replace an entire satellite constellation.

Fusion Tokamak Modified for Gravity-Wave Research: It may be possible to adapt a fusion tokamak to perform GW research.

GW Valve Concept –  Spinning HTSC in an Alternating Magnetic Field (Podkletnov): Rotating a type II superconductor through an  alternating magnetic field causes shielding via gravitational wave annihilation due to gravito-electric to gravito-magnetic frame transformation.
