Abstract
Analogic simulation is more intuitive and also enables a validation of the numerical simulation. The undulator consists of a dumb-bell wires stack. In each wire the current circulates alternatively from a wire to another. The dumb-bell contour is implemented using an analog gate controlled by a gate signal. In free-electron laser (FEL) research and development one of the main trends is the elaboration of the compact devices. The undulator is the principal component where the phenomenon of coherent radiation take place. A new theoretical model of an undulator for free electron lasers in a dumb-bell magnetic field is presented. The undulator is a stack of wires which are described in xy plane by dumb-bell equations.
