A 3D Smith Chart based on the Riemann Sphere for Active and Passive Microwave Circuits

Muller, Andrei A.; Soto Pacheco, Pablo; Dascalu, Dan; Neculoiu, Dan; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2011-06)

This letter proposes a spherical 3-D Smith Chart suitable for representing both active and passive microwave circuits. Using the mathematical concept of the Riemann sphere, the extended reflection coefficient plane is ...
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 ...
Average power handling capability of microstrip passive circuits considering metal housing and environment conditions

Sánchez-Soriano, Miguel Ángel; Quere, Yves; Le-Saux, Vincent; Quendo, Cedric; Cadiou, Stephan (Institute of Electrical and Electronics Engineers, 2014)

[EN] In this paper, the average power handling capability (APHC) of microstrip passive circuits considering the metal housing and environment conditions is investigated in detail. A systematic method is proposed for the ...
Characterization of Nematic Liquid Crystal at Microwave Frequencies Using Split-Cylinder Resonator Method

Sánchez-Marín, Juan Rafael; Nova-Giménez, Vicente; Bachiller Martin, Maria Carmen; Villacampa, Belén; de la Rua, Alberto; Kronberger, Rainer; Penaranda-Foix, Felipe L.; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers, 2019-07)

[EN] Liquid crystal (LC) is an anisotropic liquid material, which flows like a liquid, but at the same time, its molecules have an orientational order like in the solid state. Thus, LC is a promising dielectric material ...
Extending the cascading by pairs of multiport generalised scattering matrices for characterizing the connected ports

Díaz Caballero, Elena; Belenguer, Angel; Esteban González, Héctor; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2014-11)

An extension to the traditional technique for cascading generalized scattering matrices (GSMs) by pairs is presented. It can solve the connection of an arbitrary number of networks, with an arbitrary number of ports, while ...
Krylov's solver based technique for the cascade connection of multiple n-port multimodal scattering matrices

Belenguer Martínez, Ángel; Díaz Caballero, Elena; Esteban González, Héctor; Lucas Borja, Alejandro; Cascón López, Joaquín (Institute of Electrical and Electronics Engineers (IEEE), 2013-02)

In this paper, a novel technique for cascading generalized scattering matrices based on a Krylov's iterative solver is presented. This new technique is fully general, since it can be applied to solve the connection of an ...
Noninvasive monitoring of polymer curing reactions by dielectrometry

García Baños, Beatriz; Canós Marín, Antoni Josep; Peñaranda Foix, Felipe Laureano; Catalá Civera, José Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)

A microwave sensor system for the noninvasive monitoring of the curing process of a thermoset material placed inside a metallic mold is described. The microwave sensor is designed as an open-ended coaxial resonator with a ...
The 3D Smith Chart and its practical applications

Mueller, Andrei; Dascalu, Dan C.; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique (2012-07)
Wideband Electromagnetic Body Phantoms for the Evaluation of Wireless Communications in the Microwave Spectrum

Castelló Palacios, Sergio (Universitat Politècnica de València, 2019-12-02)

[ES] La constante evolución de la tecnología y la búsqueda de nuevas aplicaciones que mejoren la vida de las personas ha llevado a la incorporación de estas tecnologías en el organismo. Las redes inalámbricas de área ...
