It turned out to be compactAmerican physicists have created a compact optical analog calculator capable of solving differential and integral equations at the speed of light.Discuss
Due to slowdown Moore's law, scientists began to study the possibilities of analog computers. This is facilitated by the creation of new materials that interact with light in a new way.
Scientists in a new work proposed the use of metamaterials. They created on their basis micrometer analog computers. If irradiated with light of a certain frequency, they can instantly solve differential and integro-differential equations with high accuracy and stability.
At the same time, the scientists' model showed stability even when the authors added noise to the frequency and to the permittivity distribution. In theory, the method can also be used to solve problems for two-dimensional functions.
