Electromagnetic-artificial neural network model for synthesis of physical dimensions for multilayer asymmetric coupled transmission structures (invited article)

A methodology for synthesis (leading to physical dimensions) of multilayer asymmetric coupled microstrip lines using artificial neural network models is presented. Models are appropriate for design and optimization of multila yer configurations for circuits like filters, baluns, and directional coupl ers. Proposed methodology is demonstrated by designing a two-layer coupled line filter. (C) 1999 John Wiley & Sons, Inc.
