Time domain simulation of lossy planar networks

A time-domain finite-element method (FEM) is presented for analyzing lossy dispersive microwave planar networks. The method uses the leap-frog scheme to simulate numerically the wave propagation inside the network by solving a boundary value problem at each time step. The unique feature of this technique is that the spatial domain is discretized with first-order finite elements while the domain is discretized with finite differences. The method is illustrated with practical applications from microwave integrated circuits.<
