Optimization method and device for realizing efficient design of passive microwave device and equipment

The invention discloses an optimization method and device for realizing efficient design of a passive microwave device and equipment. The optimization method comprises the following steps: constructing an error function; determining an input sample in the optimization range, and constructing an initial training sample set in combination with full-wave electromagnetic simulation output data; training a Gaussian process model by using the training sample set, optimizing the Gaussian process model by using a particle swarm optimization algorithm to obtain an optimal design size predicted value, and simulating the optimal design size predicted value to obtain a corresponding output result; judging whether an output result meets a design index or not, if the output result meets the design index, outputting the optimal design size, and otherwise, entering the next step; calculating an error, and if a preset condition is met, updating the optimal design size; and judging whether an iteration stop condition is met or
