摘要
本文用时域有限差分(FD-TD)法研究了建筑物内电磁波传播的计算问题.首先把计算结果与联合有限元法和边界元法的结果进行了对比,而后计算了不同频率电磁波从不同方向入射时建筑物内电磁场分布的特点.并计算了线源辐射的电磁波在建筑物内的传播及向外辐射的特性以及脉冲电磁波在建筑物内传播和反射的特点.
In this paper the problems of EM wave propagation in the buildings are discussed. Using the Finite Difference Time Domain (FD-TD) method the EM field distributions in 2D buildings irradiated by plane wave are calculated. The results are compared with those obtained by the coupled Finite Element Method and the Boundary Element Method. The scattering and penetration characteristics of buildings for the plane wave with different incident directions and frequencies are calculated as well. The propagation characteristics of the EM wave radiated by 2D wire source with sinusoidal wave and Gaussian pulse wave are presented.
