Abstract :
Methods of calculating far-field quantities from a two-dimensional finite element/absorbing boundary solution of unbounded RF electromagnetic fields are presented. Three different methods are developed and compared in terms of accuracy, efficiency, and capabilities. The three methods are: harmonic expansion, Green´s theorem integral, and volume sources radiation integral
