Abstract :
The Measured Equation of Invariance (MEI) is a geometry-dependent Finite Difference equation that can be used to terminate a mesh extremely close to the object of interest. The mesh can be terminated much closer than what absorbing boundary conditions would allow, but still keeping the locality of the equations. In this paper, this new concept is applied to the numerical simulation of transmission lines and their discontinuities.
