Resumen
Numerical methods are widely used to analyze and
design microwave components for communication applications.
In the implementation of any numerical technique, however, there
are always a set of parameters that must be properly adjusted
in order to obtain, at the same time, computational efficiency
and numerical accuracy of the results. In this context, therefore,
we focus in this paper on the multimode equivalent network formulation
for waveguide devices, and we propose a more intuitive
and efficient strategy for choosing these parameters. Following
our approach, setting only one global numerical variable is sufficient
to adjust automatically the specific convergence parameters
of each discontinuity to give a specific level of numerical accuracy
of the results. As a consequence, the computational efficiency
is significantly increased. In addition, the user experience is
significantly improved since our approach eliminates all lengthy
convergence tests previously needed to ...
