1 kW微波源机箱电磁耦合的并行FDTD模拟
Electromagnetic Pulse Coupling Rule Research of 1 kW Microwave Source Case Based on Parallel FDTD Method
摘要
Abstract
Different panels of microwave source case have different numbers and sizes of rectangular holes and cooling vents. Electromagnetic pulse can couple into microwave source case by penetrating through the holes and vents, and then cause interference to the inner circuits and equipment. The adaptive mesh refine technology is used to achieve the rapid modeling of the 1 kW microwave source case. The parallel Finite-Difference Time-Domain ( FDTD) algorithm is used to simulate the coupling problems between Gaussian pulse with different polarization direction under normal incidence and the microwave source. The results show that, the numerical calculation results agree well with that simulated by electromagnetic software, and the polarization direction of electromagnetic pulse doesn’t influence the electric field strength coupling into the microwave source, and the resonant characteristics of the center of microwave source is obvious.关键词
