Great Pyramid of Giza in Egypt to focus electromagnetic energy in internal chambers

The Great Pyramid of Giza in Egypt can focus electromagnetic energy in its internal chambers and under its base, a study has found.

Researchers from ITMO University in Russia and Laser Zentrum Hannover in Germany applied methods of theoretical physics to investigate the electromagnetic response of the Great Pyramid to radio waves.

Published in the Journal of Applied Physics, the study predicts that under certain conditions the pyramid can concentrate electromagnetic energy in its internal chambers and under the base.

The research group plans to use these theoretical results to design nanoparticles capable of reproducing similar effects in the optical range.

Such nanoparticles may be used, for example, to develop sensors and highly efficient solar cells.

"While Egyptian pyramids are surrounded by many myths and legends, we have little scientifically reliable information about their physical properties," researchers said.

The physicists took an interest in how the Great Pyramid would interact with electromagnetic waves of a proportional or, in other words, resonant length.

Calculations showed that in the resonant state the pyramid can concentrate electromagnetic energy in the pyramid's internal chambers as well as under its base, where the third unfinished chamber is located.

The researchers first estimated that resonances in the pyramid can be induced by radio waves with a length ranging from 200 to 600 metres.

Then, they made a model of the electromagnetic response of the pyramid and calculated the extinction cross section.

This value helps to estimate which part of the incident wave energy can be scattered or absorbed by the pyramid under resonant conditions.

Finally, for the same conditions, the scientists obtained the electromagnetic fields distribution inside the pyramid.

The scientists conducted a multi-pole analysis. This method is widely used in physics to study the interaction between a complex object and electromagnetic field.

The object scattering the field is replaced by a set of simpler sources of radiation: multi-poles. The collection of multi-poles radiation coincides with the field scattering by an entire object, researchers said.

Therefore, knowing the type of each multi-pole, it is possible to predict and explain the distribution and configuration of the scattered fields in the whole system, they said.

The Great Pyramid attracted the researchers while they were studying the interaction between light and dielectric nanoparticles.

The scattering of light by nanoparticles depends on their size, shape and refractive index of the source material.

Varying these parameters, it is possible to determine the resonance scattering regimes and use them to develop devices for controlling light at the nanoscale.

"Egyptian pyramids have always attracted great attention. We as scientists were interested in them as well, so we decided to look at the Great Pyramid as a particle dissipating radio waves resonantly," said Andrey Evlyukhin, scientific supervisor and coordinator of the research.

"Due to the lack of information about the physical properties of the pyramid, we had to use some assumptions. For example, we assumed that there are no unknown cavities inside, and the building material with the properties of an ordinary limestone is evenly distributed in and out of the pyramid.

"With these assumptions made, we obtained interesting results that can find important practical applications," said Evlyukhin. PTI SAR SAR
