“…Previously intrigued by the relationship between the coarse and fine models in space mapping, Rayas-Sánchez was inspired by that visit to pioneer the productive connection between space mapping and artificial neural networks for RF and microwave modeling and design optimization [23], [27], [121], [122], [123]. Fruitful collaboration with Q. J. Zhang's group at Carleton University was key for the wide development of neural space mapping approaches, well-beyond Bandler's research group [29], [124], [125], [126], [127], [128], [129], [130], [131], [132], [133], [134], [135].…”

This paper outlines the early history of optimization technology for the design of microwave circuits-a personal journey filled with aspirations, academic contributions, and commercial innovations. Microwave engineers have evolved from being consumers of mathematical optimization algorithms to originators of exciting concepts and technologies that have spread far beyond the boundaries of microwaves. From the early days of simple direct search algorithms based on heuristic methods through gradient-based electromagnetic optimization to space mapping technology we arrive at today's surrogate methodologies. Our path finally connects to today's multi-physics, system-level, and measurement-based optimization challenges exploiting confined and feature-based surrogates, cognition-driven space mapping, Bayesian approaches, and more. Our story recognizes visionaries such as William J. Getsinger of the 1960s and Robert Pucel of the 1980s, and highlights a seminal decades-long collaboration with mathematician Kaj Madsen. We address not only academic contributions that provide proof of concept, but also indicate early formative milestones in the development of commercially competitive software specifically featuring optimization technology.

“…Due to the complexity of their design, manifold-coupled multiplexers have been the subject of extensive research over the last four decades [115,[157][158][159][160][161][162][163]. These multiplexers employ a common transmission line, usually a rectangular waveguide, that acts as the manifold.…”

AgradecimientosA pesar de las dudas iniciales que tenía sobre cual podía ser mi aportación a un mundo tan estudiado como el de los dispositivos de microondas en guía de onda, considero que la decisión de realizar esta tesis ha sido todo un acierto. La colaboración entre la Universidad Politécnica de Valencia y la empresa de base tecnológica Aurorasat ha permitido enfrentarme a problemas de interés científico, pero que a su vez tienen aplicación práctica directa en la industria. Agradezco enormemente a Vicente Boria por haber hecho posible esta colaboración, haberme animado a embarcarme en ella y confiado en que la llevaría a cabo conéxito. Sin su liderazgo y tenacidad, esta tesis no hubiera sido posible.Durante el desarrollo de la misma he tenido la gran suerte de contar con dos valiosos mentores, como son Jordi Gil y Pablo Soto. Para mí han sido toda una referencia tanto profesional como personal. Han sabido orientarme en momentos críticos, y su implicación ha sido total desde el primer momento. Gran parte de lo que he aprendido durante todos estos años sobre electromagnetismo y diseño de componentes de microondas se lo debo a ellos. Sin duda, este trabajo no hubiera tenido la misma calidad sin sus innumerables aportaciones.Por otro lado, también quisiera reconocer la contribución de otras personas por las que tengo gran admiración. A Carlos Vicente, por plantar algunas de las semillas que han dado lugar a esta tesis, así como por las enriquecedoras discusiones que hemos tenido todo este tiempo y el apoyo que me ha brindado. También a Santiago Cogollos, que me introdujo en el mundo BI-RME y la teoría de filtros, y que siempre ha me ha prestado una valiosa ayuda cuando lo he necesitado.Por supuesto, debo agradecer a Marco Gugliemli por permitirme explorar algunas de sus innovadoras ideas sobre filtros HFRW, y a la Prof. Kawthar Zaki por acogerme en su laboratorio de la University of Maryland. Asímismo, a mis compañeros de Aurorasat y el GAM, con los que he compartido muy buenos momentos.Porúltimo, a mi familia por todo su apoyo. Su confianza en mi capacidad para llevar a cabo esta tesis ha sido de gran ayuda para seguir adelante. A mis amigos y brothers, por estar ahí siempre. Y a Ellen, por todos losánimos que me ha dado, en especial a la hora de escribir. ivCon esta tesis se cierra un capítulo de mi vida y se abre uno nuevo. Espero que, sea donde sea, sigamos colaborando durante muchos años. Carlos Carceller AbstractModern communications systems impose stringent requirements on the equipment that operates at microwave frequency, especially in the case of wireless communications. The design of passive components for these applications is contingent upon the availability of accurate electromagnetic (EM) modeling tools that can efficiently handle the complex geometry of these components. Despite the widespread use of mesh-based general-purpose computer-aided engineering (CAE) tools to perform final design verifications, their application during the optimization process is limited. Optimum designs require a large ...
