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 ...
Análisis de imágenes mediante el método de los momentos usando funciones de base continuas a intervalos (PCBF)

Domínguez, Sergio (Universitat Politècnica de València, 2015-01-11)

[ES] Los invariantes generados a partir de momentos extráıdos de una imagen aparecen recurrentemente en la bibliograf́ıa como uno de los métodos más potentes para la descripción de imágenes, y más concretamente de formas. ...
Classical and quantum warm dense electron gas dynamic characteristics: analytic predictions

Ara, J.; Filinov, A.V.; Tkachenko Gorski, Igor Mijail (IOP Publishing, 2022)

[EN] We apply a novel 9-moment variational version of the self-consistent non-perturbative method of moments to study how the temperature affects the dynamic response of the electron gas in thermodynamic equilibrium. The ...
Dense Plasma Dynamic Structure Factor Simulation Data vs. the Method of Moments

Arkhipov, Yu. V.; Ashikbayeva, A. B.; Askaruly, A.; Davletov, A. E.; Syzganbaeva, S.; Voronkov, V. V.; Tkachenko Gorski, Igor Mijail (Wiley-VCH Verlag, 2015-05)

The dynamic structure factor of dense two-component plasmas is studied within the method of moments. A new model for the Nevanlinna parameter function is suggested. Our results on the dynamic structure factor satisfy the ...
Dynamic Collision Frequency in Kelbg-Pseudopotential-Modelled Plasmas and the Method of Moments with Local Constraints

Arkhipov, Yu. V.; Askaruly, A.; Dubovtsev, D. Yu.; Erimbetova, L. T.; Tkachenko Gorski, Igor Mijail (Wiley-VCH Verlag, 2015-05)

The dense plasma dynamic collision frequency is modeled by the first two terms of its asymptotic expansion at high frequencies and its values at a few interpolation points on the real axis. This makes the dynamic collision ...
Efficient analysis and design of devices in Substrate Integrated Waveguide (SIW) technology

Díaz Caballero, Elena (Universitat Politècnica de València, 2013-12-20)

Para abordar el análisis de estas estructuras de forma altamente eficiente, se pretenden utilizar dos enfoques distintos, que llevarían a dos técnicas distintas y eficientes, pero cada una de ellas con sus ventajas e ...
Hybrid Technique Plus Fast Frequency Sweep for the Efficient and Accurate Analysis of Substrate Integrated Waveguide Devices

Belenguer Martínez, Ángel; Esteban González, Héctor; Díaz Caballero, Elena; Bachiller Martin, Maria Carmen; Cascón López, Joaquín; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)

In this paper, we adapt a novel mode-matching and method-of-moments hybrid technique to efficiently analyze substrate integrated waveguide (SIW) based devices. The hybrid technique is formulated in terms of a single ...
ON THE COLLISIONAL ONE-COMPONENT PLASMA DIELECTRIC FUNCTION

Arkhipov, Yu. V.; Ashikbayeva, A.B.; Askaruly, A.; Conde, L.; Davletov, A.E.; Tkachenko Gorski, Igor Mijail (National Academy of Sciences of the Republic of Kazakhstan, 2013)

[EN] Asymptotic properties of the collisional one-component plasma dielectric function in the random-phase (RPA) and Mermin approximation, with a constant collision frequency, are analyzed from the point of view of ...
Stopping of charged particles in dense one-component plasmas

Arkhipov, Yu. V.; Askaruly, A.; Ashikbayeva, A.B.; Dubovtsev, Denis; Syzganbayeva, S.; Tkachenko Gorski, Igor Mijail (Al-Farabi Kazakh National University, 2018)
Sum rules and exact inequalities for strongly coupled one-component plasmas

Arkhipov, Yu.V.; Ashikbayeva, A.B.; Askaruly, A.; Bonitz, M.; Conde, L.; Davletov, A.E.; Dornheim, T.; Dubovtsev, D.Yu.; Groth, S.; Santybayev, Kh.; Syzganbayeva, S.A.; Tkachenko Gorski, Igor Mijail (John Wiley & Sons, 2018-11)

[EN] Several sum rules and other exact relations are employed to determine both the static and the dynamic properties of strongly coupled, partially and completely degenerate one-component plasmas. Emphasis is placed on ...
