The transmission line matrix method

The Transmission Line Matrix (TLM) method (or Transmission Line Modeling method, as it is sometimes called) is a key numerical method in computational electromagnetics. As a network model of Maxwells equations formulated in terms of the scattering of impulses, it possesses exceptional versatility, numerical stability, robustness and isotropic wave properties. An introduction in the two-dimensional and threedimensional TLM methods is given. The modelling of dielectric media, the use of variable and curved meshes, boundary conditions and discrete Green's functions are treated. System identification and spectral analysis approaches allow a considerable reduction of numerical effort. Further more the modelling of skin effect and nonlinear circuit elements is discussed and numerical examples are presented.     «
