The Great Pyramid can focus Electromagnetic Waves 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 length. 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. The researchers first estimated that resonances in the pyramid can be induced by radio waves with a length ranging from 200 to 600 meters. 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 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: multipoles. The collection of multipole radiation coincides with the field scattering by an entire object. 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 system. 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 Kapitainova, Ph.D., a member of the Faculty of Physics and Technology of ITMO University.
