Floquet-based FDTD analysis of two-dimensional phased array antennas

The finite-difference time-domain method with Floquet boundary conditions has been used to calculate the radiation characteristics of one- and two-dimensional phased array antennas for different scan angles in E- and H-planes. Considerable savings in computer memory and computation time are realized since only the central 3 elements for a l-D array and 3/spl times/3 elements for a 2-D array are to be modeled.<
