Abstract:
Abstract: Objective To realize the simulation and simulation calculation of the electromagnetic radiation characteristics of the real human body for grasping the changes of the electromagnetic characteristics of human tissues. Methods Based on Chinese digital visual human body data set, the method for establishing the three-dimensional electromagnetic model of the real human body was proposed, and the electromagnetic simulation calculation was carried out using CST STUDIO SUITE. Results A three-dimensional electromagnetic model of the real human head which was suitable for finite-difference time-domain calculation was constructed, with a grid precision of 1 mm3, and it satisfied the requirement of numerical dispersion for spatial discrete spacing in electromagnetic simulation below 30 GHZ frequency. Conclusion The proposed model has good visibility and maneuverability, and it has important theoretical value and practical significance for the construction of digital electromagnetic human and the optimization of biological electromagnetic detection technology.
