Abstract

A 2D discretisation of Maxwell's equations is studied in terms of the electromagnetic potentials using linear and cubic finite elements. The formulation is first analysed with respect to the discrete dispersion properties to show that it is pollution free. It is then applied to a simple cylindrical waveguide problem, showing good convergence to the analytical eigenfrequencies.
