Fast simulation method of distributed nonlinearities in surface acoustic wave resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Text en actes de congrés
Accés restringit per política de l'editorialUnderstanding the mechanism of nonlinearity in SAW/BAW devices is growing up in importance because these, even being weak, can cause desensitization of the receivers and limiting their performance. Proper nonlinear distributed ... -
Feed-forward technique to measure the reflection coefficient under CW high-power signals
(IEEE Microwave Theory and Techniques Society, 2018-10-01)
Article
Accés obertThis paper describes a measurement setup to obtain the reflection coefficient response over the frequency of a given device when this is subjected to a single-tone high-power (HP) signal. The proposed system is based on a ... -
GA design of small thin-wire antennas: comparison with Sierpinski-type prefractal antennas
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-06-30)
Article
Accés obertA new set of genetically generated electrically small thin-wire antennas with a better performance than that of several families of Sierpinsky prefractal monopoles of the same electrical size at resonance is presented -
GA design of wire pre-fractal antennas and comparison with other Euclidean geometries
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC., 2003-11-30)
Article
Accés obertA multi-objective genetic algorithm (GA) has been applied in conjunction with the numerical electromagnetic code (NEC) to the optimization of wire pre-fractal Koch-like antennas in terms of bandwidth, efficiency, and ... -

Infrared thermograms applied to near-field testing
(IEE-INST ELEC ENG, 1999-05-31)
Article
Accés obertElectromagnetic fields close to radiant structures can be measured quickly using an infrared camera. Examples of induced fields by wire antennas over a detection screen at distances shorter than one wavelength are presented. ... -

Metamateriales en microondas y antenas
(Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 2003)
Article
Accés obertDesde la década de los '80 una gran variedad de materiales artificiales (no existentes en la naturaleza) son intensivamente estudiados por sus inusitadas y sorprendentes propiedades electromagnéticas (como partes reales ... -
Method to measure reflection coefficient under CW high-power signals in SAW resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Text en actes de congrés
Accés restringit per política de l'editorialImproving power handling and lifetime are key assets to ensure device performance and reliability. SAW resonators composed by very thin cross-section inter-digital transducer (IDT) structures make difficult to control the ... -
Microstrip patch antenna design using artificial material loadings
(2010)
Text en actes de congrés
Accés obertPatch antennas filled using different material loadings, both homogeneous and dispersive, are reviewed in order to assess its FBW value. A compact formulation proposed by Yaghjian and Best [1] to compute the FBW of antennas ...
