| Abstract: | Taking the wire structures as examples, the marching-on-in-time method and the conjugate gradient method with applications to transient EM problems are studied. The relationship between the above-mentioned two methods is found and the modified conjugate gradient method given by Rao is simplified. The calculated results coincide well with the published ones. |
