    The problem posed by the fact that most numerical methods do not provide limits due to errors arising from the modeling of the structure or the numerical computations is addressed. It is shown that multiple simulations of the problem, using different but similar formulations, can overcome some of the uncertainties, without excessive computational overhead. In addition, the selection of an appropri... View full abstract»

    Scattering mechanisms that involve edge waves are addressed. The behavior of edge waves and their interaction with flat perfectly conducting plates are depicted in the time domain through a visualization of surface currents that flow on the surface, as an incident Gaussian pulse of energy washes over the surface. Viewing these surface currents allows a very clear physical interpretation and apprec... View full abstract»

    A simple moment-method solution is presented for the problem of electromagnetic scattering from structures consisting of multiple perfectly conducting and dielectric bodies of arbitrary shape. The system is excited by a plane wave. The surface equivalence principle is used to replace the bodies by equivalent electric and magnetic surface currents, radiating into an unbounded medium. A set of coupl... View full abstract»

    It is claimed that the formula for the effective area of a corner reflector given in the Radar Cross Section Handbook, vol.2 (Plenum Press, 1970, p.588) is incorrect. It is further claimed that the formula of S.D. Robertson (Bell Syst. Tech. J., vol.26, p.852, 1947) is correct, and a proof is given in support of this assertion.<> View full abstract»

    A derivation for the maximum off-boresight gain of a constant-width, variable-length rectangular aperture is presented. Also given are derivations for circular apertures, one with uniform illumination, and the other with an optimum tapered illumination.<> View full abstract»

  • Lorenz or Lorentz?

    Lorenz' work is remarkable, since it was performed in parallel with that of Maxwell. The reader will probably agree that the paternity suit must be decided in Lorenz' favour. it appears that the various authors of textbooks whi sinned against historical accuracy–the undersigned being regretfully one of them–should amend their references in future printings of their books!
