An efficient integral equation technique for the analysis of arbitrarily shaped capacitive waveguide circuits

Quesada Pereira, Fernando Daniel; Vera Castejon, P.; Alvarez Melcon, Alejandro; Gimeno Martinez, Benito; Boria Esbert, Vicente Enrique (American Geophysical Union (AGU), 2011)

In this contribution a new and efficient integral equation formulation is presented for the analysis of arbitrarily shaped capacitive waveguide devices. The technique benefits from the symmetry of the structure in order ...
An Efficient Technique to Assess the Convergence of the Multimode Equivalent Network for Waveguide Devices

Gomez Molina, Celia; Quesada Pereira, Fernando; Alvarez Melcon, Alejandro; Boria Esbert, Vicente Enrique; Guglielmi, Marco (Institute of Electrical and Electronics Engineers, 2018-02)

[EN] 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 ...
Evaluation of time domain electromagnetic fields radiated by constant velocity moving particles traveling along an arbitrarily shaped cross-section waveguide using frequency domain Green's functions

Jimenez Nogales, M.; Marini, Stephan; Gimeno Martinez, Benito; Alvarez Melcon, Alejandro; Quesada Pereira, Fernando Daniel; Boria Esbert, Vicente Enrique; Soto Pacheco, Pablo; Cogollos Borras, Santiago; Raboso García-Baquero, David (American Geophysical Union (AGU), 2012-09-21)

A technique for the accurate computation of the time domain electromagnetic fields radiated by a charged distribution traveling along an arbitrarily shaped waveguide region is presented. Based on the transformation (by ...
Multimodal Characterization of the Multipactor Effect in Microwave Waveguide Components

Jimenez, Manuel; Gimeno Martinez, Benito; Raboso García-Baquero, David; Anza Hormigo, Sergio; Alvarez Melcon, Alejandro; Quesada Pereira, Fernando Daniel; Boria Esbert, Vicente Enrique; Vicente Quiles, Carlos Pascual; Gil Raga, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2012-02)

Multipactor effect is a resonant avalanche of secondary electrons induced by an RF electromagnetic field, which endangers high-power payloads on satellites and particle accelerator structures. The main goal of this letter ...
Novel spatial domain integral equation formulation for the analysis of rectangular waveguide steps close to arbitrarily shaped dielectric and/or conducting posts

Quesada Pereira, Fernando Daniel; Gomez Molina, Celia; Alvarez Melcon, Alejandro; Boria Esbert, Vicente Enrique; Guglielmi, Marco (John Wiley & Sons, 2018-04)

[EN] In this paper, a novel integral equation formulation expressed in the spatial domain is proposed for the analysis of rectangular waveguide step discontinuities. The important novelty of the proposed formulation is ...
Nueva condición circuital para el diseño de antenas CRLH L W que presenten una tasa de radiación constante en todo el espacio

Gómez Díaz; J. S.; Martínez Mendoza, M.; Lorente, J. A.; Alvarez Melcon, Alejandro (2011)
Predicción de la sensibilidad ante tolerancias de fabricación en un filtro guía-onda butterworth

Martínez Mendoza, M.; Gómez Díaz, Juan Sebastián; Lorente, José Antonio; Alvarez Melcon, Alejandro (Universidad Politécnica de Cartagena, 2011)

En este artículo se presenta un método nuevo para la predicción de la sensibilidad en filtros Butterworth pasobanda formados por cavidades acopladas. La sensibilidad del parámetro de reflexión respecto a variaciones en los ...
