A time domain discrete model for non uniform transmission lines, based on a complementary formulation of the transmission line equations, is considered. By recasting the line equations in terms of flux and charge, one has to discretise alternatively only one of the two equations, the other being exactly verified. This approach has been widely used in electromagnetics to evaluate discretization error. With reference to simple examples, we show how the error estimation can be used for a selective meshing of the line, leading to much better approximation with the same computational effort.

Abstract
A time domain discrete model for non uniform transmission lines, based on a complementary formulation of the transmission line equations, is considered. By recasting the line equations in terms of flux and charge, one has to discretise alternatively only one of the two equations, the other being exactly verified. This approach has been widely used in electromagnetics to evaluate discretization error. With reference to simple examples, we show how the error estimation can be used for a selective meshing of the line, leading to much better approximation with the same computational effort.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
