Space mapping algorithm-based automatic computer-aid tuning design method for microwave device

Abstract

The invention discloses a space mapping algorithm-based automatic computer-aid tuning design method for a microwave device, which can accurately and efficiently automatic tune the microwave device. The method comprises the following steps of: calling an electromagnetic simulation program to establish an electromagnetic model of the microwave device, calling a circuit simulation program to establish a circuit model of the microwave device, regarding an electromagnetic model parameter set as an accurate space, regarding a circuit model parameter set as a rough space, analyzing the mapping relationship of the two spaces by a space mapping algorithm, mapping the known optimal parameter set of the rough space into the parameter set of the accurate space, adjusting the space mapping relationship by verifying the accuracy of the parameter set of the accurate space, and finally acquiring the optimal parameter set of the accurate space by multiple times of adjustment. Human-machine function expansion is performed based on implementation of a core algorithm so as to implement a series of automatic behaviors such as model update, data update, log operation and the like. The method can well improve the time and labor-wasting tuning of the microwave device, and can be used for unattended auxiliary automatic tuning microwave devices.

Description

technical field [0001] The invention belongs to the technical field of microwave device design, and in particular relates to a design method for computer-assisted automatic tuning of microwave devices. Background technique [0002] Electromagnetic simulation is a time-consuming and labor-intensive process. To promote the development of microwave technology, improving simulation efficiency is the key. [0003] The electromagnetic characteristics of microwave devices are very complex, so it takes a lot of time and effort to tune in the design process. At present, this process mainly relies on manual experience, and the tuning of microwave devices with complex structures is not certain and stable. Therefore, in order to reduce the difficulty of microwave device tuning and reduce the influence of human factors on tuning efficiency as much as possible, it is necessary to study the automatic tuning method of microwave devices. [0004] Although electromagnetic simulation is more ...

Problems solved by technology

However, if you want to use simulation programs from different companies for co-simulation, you will still encounter the problem of inconsistent interfaces. Some simulation products with superior performance do not even provide external interfaces, and can only be simulated completely by manual operation.

In the optimization process, it is often a repetitive operation. If the program is manually operated every time, the efficiency of computer simulation cannot be fully utilized.
