    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 ...

    A New Reference Sample for High-Frequency Multipactor Testing 
    González-Santatecla, Pablo; Smacchia, Davide; Alcaide-Guillén, Carlos; Soto Pacheco, Pablo; Rodríguez Pérez, Ana María; Morro, J. V.; Mata-Sanz, Rafael; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers, 2023-06)
    [EN] Multipactor (MP) is a high-power effect severely limiting the performance of satellite communication links. A reference sample is normally used in the experimental setups for MP testing in order to verify its correct ...

    Efficient Design of Waveguide Manifold Multiplexers Based on Low-Order EM Distributed Models 
    Cogollos Borras, Santiago; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique; GUGLIELMI, MARCO; Brumos Vicente, María; Gimeno Martinez, Benito; Raboso García-Baquero, David (Institute of Electrical and Electronics Engineers (IEEE), 2015-08)
    In this paper, a new systematic technique to design manifold-coupled multiplexers in waveguide technology is proposed. The new technique uses generalized low-order electromagnetic (EM) distributed models, which constitute ...

    Multipactor Threshold Estimation Techniques Based on Circuit Models, Electromagnetic Fields and Particle Simulators 
    González-Santatecla, Pablo; Alcaide, Carlos; Cervera, Raúl; Rodríguez, Miguel; Monerris, Óscar; Petit, John; Rodríguez Pérez, Ana María; Vidal Pantaleoni, Ana; Vague, Joaquín; Morro, J. V.; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers Inc., 2022-01-07)
    [EN] Multipactor has become a keylimiting factor of the final performance of satellite communication systems, due to the increase in power levels and/or operating frequency bands. As a result, the critical components of ...

    Propagation Characteristics of Groove Gap Waveguide Below and Above Cutoff 
    Berenguer Verdú, Antonio José; Fusco, Vincent; Zelenchuk, Dmitry E.; Sánchez-Escuderos, Daniel; Baquero Escudero, Mariano; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2016-01)
    Recently, gap waveguides have been shown as a potential alternative to convenational waveguides in the millimeter-wave band. Until now, groove gap waveguide (GGW) has been studied through direct correspondence with rectangular ...

    Systematic Procedure to Avoid Unintended Polarity Mismatch in the Cascade Connection of Multiport Devices with Symmetric Feeding Lines 
    Belenguer Martínez, Ángel; Borja, A.L.; Díaz Caballero, Elena; Esteban González, Héctor; Boria Esbert, Vicente Enrique (Institution of Engineering and Technology (IET), 2015-08-20)
    The traditional cascading of generalised scattering matrices (GSMs) assumes that the modal sets at the connected ports of a cascaded network are strictly equal. This implies a careful selection of the modal polarities, or ...
