时域物理光学后向散射近场线积分表达式
Time-domain physical-optics line-integral representations of back scattered near-fields
摘要
Abstract
A time-domain physical-optics (TDPO) line-integral representation is developed for the backscattered near-fields from a perfectly conducting surface illuminated by a dipole resource.The pro posed representation is derived from time-domain physical-optics(TDPO) surface-integral representation by introducing two theorems:surface gradient theorem and surface divergence theorem.The proposed representation is free from singularities for all the source/observer positions in which the dipole antenna is located.The transient backscattered magnetic fields of metal plate and a complex object are computed.The results are in good agreement with those obtained by other methods.Numerical results show that the method can not only ensure the calculation accuracy,but also greatly improve the calculation speed.关键词
