摘要 分析了电磁(EM)场在有损耗左手材料(LHM)模型中能量与损耗因子间的关系,推导了有耗LHM模型的时域有限差分法(FDTD)计算公式,数值模拟了EM场在该有耗LHM材料模型中的传播;对比无耗与有耗LHM模型的EM聚焦特性,分析EM场在不同损耗因子LHM材料中的传播。研究表明,数值结果与理论分析得到较好吻合。 Electromagnetic(EM) energy with loss factor in lossy left-handed materials(LHM) was analyzed. Finite-different time-dornain(FDTD) formulas of lossy LHM were derived. Propagation of EM field in lossy LHM was simulated. Comparison of EM focus in lossless and lossy LHM was made, Amplitude of electric fields with different loss factors in LHM were compared. Good agreement can be observed between theoretical analysis and numerical simulations.
