Logic Elements for Analog Calculations Based on Multi-slit Interference of Microwave

One of the possible optical computing methods is the use of multi-slit interference. The accuracy of various multi-slit optical experiments is difficult due to the difficulty of creating appropriate narrow slits for diffraction experiments with 2, 3 or 4 slits. The solution to these and similar technical difficulties may be to change the radiation spectrum from the classical optical range to the microwave region. This article presents preliminary two- and three-slit interference microwave test experiments. To obtain interference, various dielectric bases with metal coatings with two and three slits of different widths were used. Diffraction experiments were performed for microwave frequencies in the range from 36.3 to 53.6 GHz. The possibility of controlling microwave two- and three-slit interference by changing the polarization or introducing a time delay in the path of radiation propagation is shown. In particular, an almost complete mutual attenuation of the signal in the center of the microwave beam was obtained during interference from two slits with a phase shift of radiation from the left and right slits. The study searches for quantum effects in the near Fresnel zone and the far Fraunhofer zone. The possibility of computer simulation of wave scattering on various two-dimensional and three-dimensional objects (microwave converters) is discussed.
