Optimization-Oriented Design of RF/Microwave Circuits Using Inverse-Linear-Input Neuro-Fuzzy-Output Space Mapping with Two Different Dimensionality Simulators
In this paper, an efficient optimization technique
aligning three-dimensional (3-D) electromagnetic simulator responses with two-dimensional (2-D) electromagnetic simulator
responses around space mapped solution, for the electromagnetic
design of radiofrequency and microwave 3-D circuits is presented.
The interface between 2-D and 3-D electromagnetic simulators is
obtained from an inverse linear input space-mapping approach
and an output modeling process based on a fuzzy logic technique.
It is shown that the technique provides a highly accurate estimation of the 3-D design parameter space of the 3-D radiofrequency
and microwave circuits to be designed, for initially fixed design
specifications. Designs of first-order, second-order and sixth-order
C-band 3-D evanescent rectangular waveguide bandpass filters
with dielectric posts show the performance of our approach.This work was supported by Ministerio de Educaci贸n y Ciencia of Spain (TEC2007-67630-C03-02/TCM)
