Electromagnetic absorption power density evaluation method and system, electronic device

Abstract

This application relates to the field of electromagnetic absorption power density assessment technology, and discloses an electromagnetic absorption power density assessment method, including: acquiring the incident electromagnetic wave parameters of the scene to be assessed, the geometric model of the target object, and the organization electromagnetic parameters; inputting the above parameters into the assessment model to obtain the predicted result of the electromagnetic absorption power density distribution and its spatial uncertainty distribution; sampling the real scene to obtain measured data, the sampling strategy being determined by the spatial uncertainty distribution; optimizing the model parameters based on the comparison between the measured data and the predicted results; and finally, re-evaluating the optimized model by inputting the parameters into the model. This application achieves rapid prediction and uncertainty quantification by constructing a digital twin and physical verification closed loop, intelligently guiding measurement resources with uncertainty distribution, and calibrating the model using measured physical data, thereby improving assessment efficiency, accuracy, and reliability. This application also discloses an electromagnetic absorption power density assessment system and electronic device.
