An international research group has applied methods of theoretical
physics to investigate the electromagnetic response of
the Great Pyramid to radio waves.
Scientists predicted that
under resonance 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
nanoparticles may be used, for
example, to develop sensors and highly efficient solar cells.
The study (Electromagnetic
Properties of the Great Pyramid - First Multipole Resonances and
Energy Concentration) was published in the Journal of
While Egyptian pyramids are surrounded by many "myths" and
"legends", researchers have little scientifically reliable
information about their physical properties.
Physicists recently took
an interest in how the Great Pyramid would interact with
electromagnetic waves of a resonant
Calculations showed that
in the resonant state, the pyramid can concentrate
electromagnetic energy in the its
internal chambers as well as under its base, where the third
"unfinished" chamber is located.

These conclusions were derived on the basis of numerical modeling
and analytical methods of physics.
first estimated that resonances in the pyramid can be
induced by radio waves with a length ranging from 200 to 600
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
Finally, for the
same conditions, the scientists obtained the electromagnetic
field distribution inside the pyramid.
In order to explain the
results, the scientists conducted a multipole 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:
The collection of
multipole radiation coincides with the field scattering by an entire
Therefore, knowing the
type of each multipole, it is possible to predict and explain the
distribution and configuration of the scattered fields in the whole
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.
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.
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.
assumptions made, we obtained interesting results that can find
important practical applications," says Dr. Sc. Andrey Evlyukhin,
scientific supervisor and coordinator of the research.
Now, the scientists plan
to use the results to reproduce similar effects at the nanoscale.
"Choosing a material
with suitable electromagnetic properties, we can obtain
pyramidal nanoparticles with a promise for practical application
in nanosensors and effective solar cells," says Polina
