Passive Manipulation of Gravito-Photons with Metamaterials?

In H.G. Wells' novel The First Men in the Moon a scientist discovers "cavorite", a mineral impervious to gravity that can also shield other materials from its effects. The search for materials with the ability to modify gravity have long been considered science fiction. But recently a paper by Minter, Wegter-McNelly and Chiao suggested that hypothesized High Frequency Gravity Waves (HFGWs) might be able to be reflected like a mirror by thin superconducting films when Cooper pairs are in motion. http://arxiv.org/abs/0903.0661

Whether this will be the case is uncertain and Chiao has had some setbacks with his "gravity-radio" experiments in 2003, but of greater interest to myself is not whether any passive material may be able to interact with gravity waves or gravitons to redirect their paths, but whether there are materials that would be able to interact with gravito-photons, the hypothesized particles in Extended Heim Theory.

My candidate would be metamaterials.

Metamaterials have been modeled to manipulate photons to create invisibility cloaks in a manner analogous to the warping of space by gravity. Researchers such as Ulf Leonhardt of the University of St. Andrews, John Pendry of Imperial College London and Dr Guenneau, at the University of Liverpools’s Department of Mathematical Science are just a few of the theoreticians that have made clear the potential of metamaterials.

They have also shown how metamaterials can mimic phenomena that have been associated with manipulations of space-time. Dr. Guenneau, explains. “Using this new computer model we can prove that light can bend around an object under a cloak and is not diffracted by the object. This happens because the metamaterial that makes up the cloak stretches the metrics of space, in a similar way to what heavy planets and stars do for the metrics of space-time in Einstein’s general relativity theory. http://www.physorg.com/news97945163.html

Ulf Leonhardt of the University of St Andrews in the UK working independently of John Pendry of Imperial College London, says, "This research shows how much electromagnetic or optical instruments can do... Interestingly, the new calculations are inspired by the geometry of curved space -- a discipline that is normally in the firm hands of researchers in general relativity."

There was also an article http://www.space.com/scienceastronomy/080306-blackhole-fiber.html and news release on the creation of a fiber-optical analogue of the event horizon of a black hole. It simulated a gravitational phenomenon through the use of photonic-crystal fibers. A description of other instances of this effect is here: http://www.st-andrews.ac.uk/~ulf/fibre.html.

A paper published in the March 2009 issue of Society for Industrial and Applied Mathematics Review, "Cloaking Devices, Electromagnetic Wormholes, and Transformation Optics," presents an overview of the theoretical developments in cloaking from a mathematical perspective. The cloaking version of a wormhole allows for an invisible tunnel between two points in space through which electromagnetic waves can be transmitted. http://dx.doi.org/10.1137/080716827

With such a close relationship between metamaterials and optical analogues of gravity events, and the generation of gravito-photons through gravito-magnetic interactions, perhaps one day metamaterials will be able to be designed to passively interact with propulsion or standing fields produced by gravito-photons. This might include the ability to pass through them, reflect them, or shape them to form gravito-lenses on a small scale.

AIAA Lecture Series

The American Institute of Aeronautics and Astronautics (AIAA) is sponsoring a dinner lecture series this month in Sacramento, California featuring a presentation by Dr. Jochem Häuser, co-author with Walter Dröscher on Extended Heim Theory.

The announcement reads as follows:

Dr. Häuser will be joining us from Saltzgitter, Germany, to present: Emerging Physics for Novel Field Propulsion Abstract: In this talk we present and discuss novel physical concepts that might lead to advanced space propulsion technology based on novel gravitational-like force fields. Such a propulsion technology would be working without propellant. This technology is based on the existence of two additional gravity-like fields, which are gravitational fields that are not described by conventional gravitation.

The paper begins with an introduction of the present theoretical and experimental concepts pertaining to the novel physics of these gravity-like fields. In the following section, the latest gravitomagnetic experiments performed at ARC Seibersdorf (2008) [refers to research by Dr. Martin Tajmar - editor] are analyzed, and a qualitative explanation for the highly varying measured results is given.

In section three, the physical basis (termed Extended Heim Theory, EHT) employed in the explanation of the ARC experiments is presented. EHT, based on the construction of a poly-metric (geometric approach), which is obtained by providing each point of external spacetime with an internal 8D space (Heim space), requires the existence of six fundamental interactions, three gravitational fields, which are both attractive and repulsive as well as the known electromagnetic, weak, and strong forces. Moreover, from the interpretation of the poly-metric, the existence of ordinary matter (fermions and bosons) as well as non-ordinary matter (virtual imaginary particles as well as stable neutral (heavy) lepton particles with rest mass) is postulated.

It is shown that conservation principles need to be applied to the complete physical system containing both types of matter. Furthermore, it is argued that the re-interpretation of the general symmetry breaking mechanism leads to virtual particles of imaginary mass, which in turn, should be responsible for the conversion of electromagnetic into gravitational energy (ARC experiments).

In section four, based on this conversion, the physical mechanism underlying the ARC experiments is discussed and comparison of EHT predictions and measured results are given. Arguments will be provided to ensure the consistency of the ARC measurements. The last section, based on the results of EHT, is dedicated to describe a novel experiment for the generation of a gravity-like field (acceleration field) that could serve directly as a propulsion principle, since the direction of the force should be along the axis of rotation of the disk (ring in ARC experiments) and not in the circumferential direction as is the case in the ARC experiments. Furthermore, the scaling of this experiment will be discussed and calculations will be given that show that a substantial force should be producible with current technology.

In the Conclusions the validity and consistency of gravitomagnetic experiments performed is argued and their relation to the existence of six fundamental forces is debated. The widespread scientific and technological consequences of gravity-like fields in the general area of transportation (earthbound, air and space), physics as well as cosmology are also outlined. Finally, recommendations are made how the state of gravity-field like research could be advanced both theoretically and experimentally.
