Abstract :
In this paper, a finite-difference time-domain (FDTD) analysis of a stripline disc junction circulator is presented. Magnetic fields inside the finite-size ferrite disks are calculated using special updating equations derived from the equation of motion of the magnetization vector and Maxwell´s curl equations in consistency. Frequency dependent circulator parameters are calculated over a wide band of frequencies with a single FDTD run.
