We present an efficient near-to-far-field transformation technique to be used in conjunction with the body of revolution finite-difference time-domain (BOR/FDTD) algorithm. The efficiency is gained by factoring out the azimuthal angle /spl phi/ from the two-dimensional (2D) far-field integration usi...
