Abstract :
The physical origin of the coarseness and dispersion errors affecting TLM solutions of Maxwell´s equations is investigated. The study is performed by solving the difference equations of the method analytically. The results confirm a reduction of the accuracy of the discrete solution near field singularities. This effect is a consequence of the finite number of spatial modes supported by the discretized domain.
