Abstract
Electromagnetic wave analog computing is an effective method to overcome the bottleneck of electronic computing, which has attracted the attention of scientists. However, many spatial analog signal processing systems based on electromagnetic waves can only execute one unique mathematical operator and cannot provide multiple operators for users to choose arbitrarily. In order to enhance the function of the current spatial analog computing system, we design a coding structure with amplitude-phase decoupling modulation to realize the analog signal processor that supports the switching of mathematical operators and demonstrate the precise switching from the first-order spatial differential operator to the first-order spatial integral operator. Our design idea can be used as a paradigm for designing small reconfigurable analog computing systems, paving the way for the construction of high-speed, multifunctional, and universal signal processing systems. This idea can be extended to any other range of waves.
