Ultra-wideband cylindrical antenna design using the Green's function method (GFM) as an absorbing boundary condition (ABC) and the radiated field propagator in a genetic optimization

An ultra-wideband antenna is designed using genetic optimization and the finite-difference-time-domain (FDTD) method. Efficiency is enhanced by using the Green's function method (GFM) as an absorbing boundary condition (ABC) close to the antenna surface, and as a propagator to the radiated field at any observation point at each iteration step. © 2005 Wiley Periodicals, Inc.
