Abstract :
A novel technique to implement periodic boundary conditions for unit cell analysis of infinite phased arrays in the finite difference time domain (FDTD) is presented. It allows for pulse excitation and oblique scan directions in both the cardinal and inlet cardinal planes. The ordinary Yee lattice is used which makes the algorithm easy to incorporate in an already existing FDTD code.
