Abstract | Refined optimisation of complex curve-linear shaped
radiators, such as travelling wave Vivaldi antennas, can be
achieved by considering simulated near-fields to interpret in
detail the structural influences of a design. The relationships
between space- and time- distributions of electromagnetic (EM)
energy clusters and the geometric features are revealed with
appropriate use of impulse response analysis combined with
the MUSIC algorithm. This article reports a deeper approach
when applied to the adjustment of the geometric features of
a travelling wave antenna based on analysis of near-fields
propagation features.
