This paper presents a quasi-analytic solution for the transient analysis of scattering from a general, finite hyperbolic surface when it is illuminated by a plane wave. This solution significantly extends the applicable scope of the solution in [1], to simulate realistic scatters with both convex and concave surface curvatures. Since TD-PO is used, the solution can be used to predict the early time,...
A time-domain formulation of the uniform geometrical theory of diffraction (TD-UTD) is developed for predicting the transient radiation and surface fields of elemental pulsed antennas placed directly on a smooth perfectly conducting, arbitrary convex surface. The TD-UTD solution is obtained by employing an analytic time transform (ATT) for inverting into time the corresponding frequency domain UTD...
This paper we presented a quasi-analytic TD solution to perform a transient analysis of scattering from a parabolic reflector antenna when it is illuminated by a general GB. This approach is quite useful in practical applications of reflector antennas since the GB can be flexibly used to model a variety of antenna feeds.
