Se han realizado más de veinte vídeos [...]texto impreso
Bernardino Santos, Teodoro ; Antoranz Canales, Pedro ; Miranda Pantoja, José Miguel ; Sebastián Franco, José Luis | IEEE | 2007This work aims to illustrate how the transmission line theory may yield to strong errors in predicting the reflection coefficient at the input of a short - circuited coaxial transmission line when the inner conductor is either thin enough or los[...]texto impreso
An undergraduate experiment is proposed to facilitate the understanding of the basic principles related to radar systems and signal analysis. A Doppler-effect radar has been installed and used to measure the velocities of a target under differen[...]texto impreso
We present microwave noise measurements performed on different high electron mobility transistor channels under both darkness and illumination. Two structures of Alo(0.3)Gao(0.7)As/GaAs layers have been grown with beams of Asp and As-4 using mol[...]texto impreso
Miranda Pantoja, José Miguel ; Sebastián Franco, José Luis | IEEE-Inst Electrical Electronics Engineers Inc | 2000-11This paper presents the fabrication, experimental characterization and modeling of 0.15 mum gate-length lattice matched MODFETs based on InP technology. The variation of the drain noise temperature of the Pospieszalski model (T-D) with the appli[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel | Elsevier Science SA | 2004-08This paper studies the internal electric field distribution in human erythrocytes exposed to MW radiation. For this purpose, an erythrocyte cell model is exposed to linearly polarized electromagnetic (EM) plane waves of frequency 900 MHz and the[...]texto impreso
Miranda Pantoja, José Miguel ; Sebastián Franco, José Luis | IEEE- Inst. Electrical Electronics Engineers Inc | 1997-06A calculation of the electron velocity in heavily doped GaAs has been performed. A model to account for the LO phonon-plasmon coupling effects is proposed in a full Monte Carlo simulator; we believe this is the first time this fact has been trie[...]texto impreso
Miranda Pantoja, José Miguel ; Sebastián Franco, José Luis | IEEE-Inst. Electrical Electronics Engineers Inc | 2000-07A simulation at microscopic level of the intrinsic microwave noise temperature associated to GaAs and InP semiconductors under far from equilibrium conditions has been performed. The dependence of the noise temperature on the electric field, dop[...]texto impreso
We have investigated the noise performance of HEMT devices for low noise operation with the aim of developing a noise model valid for low power biasing. Analytical expressions useful for CAD models have been derived for the calculation of the Po[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Álvarez Galindo, Gabriel | American Physical Society | 2008-11We show that within the dipole approximation the complex polarizability of shelled particles of arbitrary shape can be written as the volume of the particle times a weighted average of the electric field in the particle, with weights determined [...]texto impreso
This work presents a procedure to reduce effectively the uncertainty of noise measurements of highly reflective one-port DUT's. This procedure consists of inserting an attenuator between the calibration reference plane and the DUT. The measureme[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Miranda Pantoja, José Miguel | Horizon House Publications Ltd | 2004In this paper a simple experimental set-up is presented to determine the complex dielectric permittivity of biological tissues at the industrial frequency of 2.45 GHz. For this purpose, the scattering parameters of biological samples, which are [...]texto impreso
Muñoz San Martín, Sagrario ; Sebastián Franco, José Luis ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel | IOP publishing ltd | 2003-06-07This paper shows the importance of using realistic cell shapes with the proper geometry and orientation to study the mechanisms of direct cellular effects from radiofrequency (RF) exposure. For this purpose, the electric field distribution withi[...]texto impreso
Muñoz San Martín, Sagrario ; Sebastián Franco, José Luis ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel | Wiley-Liss | 2004-12In this article, the transmembrane voltage induced on erythrocyte, codocyte, ovalocyte and spherocyte cell models exposed to a linearly polarised electromagnetic plane wave of frequency 1800 MHz is calculated. For this purpose, a finite element [...]
