Electromagnetic properties of the pyramids from the photonics position
The work substantiates the choice of the working wavelength of electromagnetic radiation for the pyramid, considered as an antenna. It is shown that due to the strong dispersion of the refractive index of the pyramid material, there will always be a band of the spectral range in which the refractive index corresponds to the localization condition of the electromagnetic wave (the effect of a photonic jet). It is shown that the pyramid can simultaneously serve as a transmitting antenna both at the fundamental frequency and at multiple frequencies. Our consideration and approach is not limited to the shape of the pyramid of Cheops and can be generalized to all other forms of the known pyramids. It can be assumed that, despite the difference in the shape of the pyramids around the world, while observing the principle of mesoscaled, such structures can play the role of antennas.
