The Weakly Conditionally Stable HIE-FDTD Method Including Lumped Networks

The weakly conditionally stable HIE-FDTD method including the lumped networks is proposed, which based on the bilinear Z-transform technique. Firstly, in this method, the current density of lumped networks is obtained in the Laplace domain. Then, it is transformed from the S-domain to the Z-domain and from the Z-domain to the time domain. In the time domain the current density can be introduced into the algorithm. Finally, the effectiveness and computational accuracy of the weakly conditionally stable HIE-FDTD scheme is verified by comparison with ADS and the traditional HIE-FDTD method.
