Research on Unexpected Electromagnetic Energy Coupling and Energy Release in High Field Strength Environments

In response to the diverse functional requirements of weapon platforms, the design process of weapon platforms faces the challenging task of high radiated energy aggregation and co-location of high-sensitivity devices. Although electromagnetic compatibility design allows for basic compatibility in the electromagnetic domain, the presence of high radiated energy in the near field poses challenges for cross-physical field adaptability of co-located devices. This results in performance degradation of co-located devices in the electromagnetic domain and gives rise to unexpected electromagnetic compatibility issues. This study investigates and summarizes the unintended electromagnetic energy coupling and energy release caused by front-door and backdoor coupling effects, providing guidance for the identification and resolution of similar issues in subsequent research.
