Resumen
Descripción
For the first time, an automated design procedure
based on space mapping techniques is developed for the EMbased
optimization of left-handed coplanar waveguide (CPW)
filters based on split ring resonators (SRRs). Our design procedure
is based on a constrained Broyden-based input multistage
space mapping strategy, using a statistical approach to
parameter extraction (PE). Pre-conditioning of the coarse model
design parameters is used at each PE iteration, imposed by
the severely bounded region of validity of the equivalent circuit
model. The space mapping algorithm effectively aligns equivalent
circuit responses with simulated results provided by full-wave
electromagnetic simulation tools. Our method is illustrated by
the EM-based design of a CPW bandpass filter with 3 SRRs.
