Geometrical and Topological Methods in Time Domain Antenna Synthesis
Abstract
The nonlinear version of Lorentz Reciprocity cannot be articulated in terms of frequency domain concepts. Similarly, the fact that a Fourier Transform relates an antenna's far field to its sources cannot be used to explain why electromagnetic bullets or missiles cannot exist since, by construction, there is no far field for a bullet. Over the last year it has become clear that one has to deal with Maxwell's Equations as a system of hyperbolic p.d.e.'s and avoid the temptation of using elliptic theory which is applicable when taking a Fourier Transform (as engineers are trained to do) and playing with Helmholtz's equation. The way to achieve these goals is to reexamine the 'raison d'etre' for the use of the Radon transform in these hyperbolic problems.
