- Аннотация: Adiabatic superconducting neurons are single- and double-junction interferometers, shunted with additional inductance. The required shape of the activation function is achieved at certain values of the inductance of the parts of the neuron. Therefore, numerical modeling of the sample design is of great importance, since it allows for the calculation of the necessary values and predicts the shape of the transfer function. Currently, there are several programs for this purpose, two of which were developed [1-2] by one of the co-authors. We report the first systematic study of the applicability of wxLL and 3D-MLSI programs for designing Josephson interferometers. We have calculated the inductance of the loops of two-junction interferometers placed above a superconducting screen. Then, a comparison was made with the results of an experimental study of samples fabricated using the USE «Cryointegral» (USE No. 352529) of the V.A. Kotelnikov Institute of Radio Engineering and Electronics of the Russian Academy of Sciences. The good coincidence of calculated and experimental data allows us to expect the successful implementation of neuromorphic Josephson interferometers. Obtained experimental temperature dependencies reveal the possibility to adjust the superconducting sigma-neuron transfer function. References: [1] M.M. Khapaev, A.Y. Kidiyarova-Shevchenko, P.
