An international interrogation grouping applied methods of theoretical physics to investigate the electromagnetic answer of the Great Pyramid to radio waves. Scientists predicted that nether resonance atmospheric condition the pyramid tin locomote concentrate electromagnetic unloose energy inwards its internal chambers too nether the base. The interrogation grouping plans to usage these theoretical results to pattern nanoparticles capable of reproducing like effects inwards the optical range. Such nanoparticles may last used, for example, to prepare sensors too highly efficient solar cells. The report was published inwards the Journal of Applied Physics.

These conclusions were derived on the terra firma of numerical modeling too analytical methods of physics. The researchers source estimated that resonances inwards the pyramid tin locomote last induced past times radio waves alongside a length ranging from 200 to 600 meters. Then, they made a model of the electromagnetic answer of the pyramid too calculated the extinction cross section. This value helps to guess which usage of the incident moving ridge unloose energy tin locomote last scattered or absorbed past times the pyramid nether resonant conditions. Finally, for the same conditions, the scientists obtained the electromagnetic fields distribution within the pyramid.
The Great Pyramid attracted the researchers spell they were studying the interaction betwixt lite too dielectric nanoparticles. The scattering of lite past times nanoparticles depends on their size, shape too refractive index of the source material. Varying these parameters, it is possible to determine the resonance scattering regimes too usage them to prepare devices for controlling lite at the nanoscale.
"Egyptian pyramids accept e'er attracted dandy attention. We every bit scientists were interested inwards them every bit well, too thus nosotros decided to await at the Great Pyramid every bit a particle dissipating radio waves resonantly. Due to the lack of information near the physical properties of the pyramid, nosotros had to usage approximately assumptions. For example, nosotros assumed that at that topographic point are no unknown cavities inside, too the edifice fabric alongside the properties of an ordinary limestone is evenly distributed inwards too out of the pyramid. With these assumptions made, nosotros obtained interesting results that tin locomote discovery of import practical applications," says medico Sc. Andrey Evlyukhin, scientific supervisor too coordinator of the research.
Now the scientists innovation to usage the results to reproduce like effects at the nanoscale. "Choosing a fabric alongside suitable electromagnetic properties, nosotros tin locomote obtain pyramidal nanoparticles alongside a hope for practical application inwards nanosensors too effective solar cells," says Polina Kapitainova, Ph.D., a fellow member of the Faculty of Physics too Technology of ITMO University.
