Evaluation of IEMI Effects on Drone Flight Controllers and Performance Analysis of Shielding Materials

This study measures the frequency and electric field intensity of intentional electromagnetic interference that directly disrupts inertial measurement unit (IMU) data in drone flight controllers (FCs) and evaluates the material-specific shielding performance of nanomaterial-based electromagnetic enclosures. FC vulnerability analysis in the sub-1 GHz band revealed accelerometer and gyroscope disruptions at 390 MHz with 750 V/m. Applying the shielding enclosures under identical conditions confirmed material-specific electromagnetic immunity by observing differences in IMU disruption, enabling meaningful analysis based on disruption patterns.
