摘要：

This letter describes an accurate two-dimensional (2-D) hard-source model for finite-difference time-domain (FDTD), The proposed model allows accurate control over the effective radius of a 2-D hard source. In addition, the TM version of the source model is directly applicable as a very accurate 2-D thin-wire model. The proposed model is verified in 2-D for both TM and TE case using a recently introduced method for finding the effective radius of a filamentary 2-D hard source [1].
