ELF EM Gravity Shield Theory And Experiment Design


Presentation Objective Present an experimental design model for a gravity shield apparatus based on a theory evolved over the last two decades. The model is an approximation meant to be a starting point for experimental analysis. • Point out there is currently no reproduced gravity shield experiment data in the literature • Give historical account of this particular gravity shield theory • Model an experimental apparatus for theory validation • Present experimental efforts to date

THE VERDICT IS STILL OUT!!!


DeAquino Derives The General Case 1999


Current Status • DeAquino (2002) derived his mg equation directly from the energy Hamiltonian eliminating D&H dependency and Barton uncertainty • Calculation is for electromagnetic radiation (EM) so must assume same effect for EM illumination • Assumes a weightless container will result in weightlessness inside the container volume (gravity cannot stop then start) • Experiments are difficult to design because of the low frequency power densities required (order of several kilowatts per square meter at 100 Hz in a small volume)

An analysis of this Equation shows an antenna surrounded by a medium with slight conductivity and high permeability can efficiently radiate power in the ELF range.

Dipole Radiation Efficiency An antenna radiation efficiency of 100% means all input power is radiated and no heat is dissipated from ohmic resistance (assume resonant so ignore the near field).

eff =

Rr Rr + Rohmic

Ohmic resistance for a copper antenna element conductor is:

Rohmic ≈

z ωµ 2πa 2σ

where: Rohmic = antenna element electrical ohmic resistance, z = antenna element length, a = antenna element radius, µ= 4π E-7 for copper, σ= 5.7E+7 for copper.

η = 1 − e − kα x where: w = 2*π*f, f = antenna radiated frequency (Hertz), ε0 = permittivity in vacuum, εrM = permittivity of medium, µ0 = permeability in vacuum, µrM = permeability of medium, σM = conductivity of medium (S/meters), α = EM attenuation real attenuation coefficient, k = radiation absorption resonance constant (k ~ unity for ELF), x = thickness of medium material (meters), η = radiation absorption coefficient.

Eta is a less than unity multiplier correcting for the EM energy absorbed by the surrounding medium.


Radiation Power Density For this example geometry, cylinder shield surface illumination energy is radiated power divided by shield surface area (assuming no near field):

D =

where: r = radius of surrounding shield (meters), h = length of surrounding shield (meters), Pr = antenna radiated power (Watt), D = antenna radiated power density (Watt/meters^2).
