Abstract :
Planar microwave circuits are simulated by a mixed space-spectral domain integral method which allows the consideration of space-varying impedances. For an efficient computation of scattering parameters of circuits containing lumped elements within this fullwave analysis, a bilinear transformation is used. Furthermore, by this so-called Mobius transformation it is possible to decide whether an impedance region of finite size can be interpreted as a lumped element or not. Applications to microstrip circuits are discussed
