CST-based System-level Electromagnetic Compatibility Analysis And Software Design

With the continuous development of modern electronic information systems, electromagnetic environment has become increasingly complex, EMC analysis of the systems with multiple antennas and cable networks becomes more and more difficult. The analysis of electromagnetic compatibility with software simulation takes more attention. Commercial software is becoming more nature, but as an universal software it does not have professional EMC analysis, and because of the complexity of the EMC analysis process, we need for secondary development to achieve integration and automation of some functions. This article accomplished the system electromagnetic compatibility assessment of prediction and the simulation software design.First, this thesis studied the CST control technology based on VBA and completed the automatic analysis process design of antenna coupling. In addition, it illustrated the basic theory of antenna coupling, simulated a complex background system with multi-antenna based on CST, arrived at a result of the mutual coupling between different antenna collection, for different engineering applications, gave a set of general principles and techniques of antenna EMC design and engineering implementation, which could be regarded as a theoretical guidance for the actual design and development. For the accomplishment of CST-based system-level electromagnetic compatibility predictive analytic software, wherein, the antenna set coupling was one of the two main elements including cable crosstalk coupling analysis.Secondly, it explained the basic theory, the general process, the development of applications of genetic optimization algorithm as well as for the realization of the optimization process design of antenna coupling, etc.Thirdly, this thesis studied the CST control technology based on VBA, API functions and completed the automatic analysis process design of cable coupling. In addition, It Clarified the relevant theoretical analysis method for the cable crosstalk coupling, based on CST simulation, analyzed the used different cable crosstalk coupling with each other, arrived at crosstalk the results, for different engineering applications, gave a set of general principles and techniques including cables selection, which could be regarded as a theoretical guidance for the actual cable selection and wiring. For the accomplishment of CST-based system-level electromagnetic compatibility predictive analytic software, wherein, the cable crosstalk coupling was one of the two main elements including antenna set coupling analysis.Finally, software implementation was illustrated, it elaborated the software design, the frame structure, and the control processes, etc. Combined antenna coupling analysis and cable coupling analysis of the system’s two main aspects, With the use of the final completion of the overall software design and development, this article gave a more complex integrated numerical example, which was in the background of the missile model, carried out between the antennas and cables EMC simulation analysis, and including the simulation analysis conclusion.
