Text en actes de congrés.
Accés restringit per política de l'editorial
Systematic spatial errors in SMOS brightness temperature images are successfully estimated by using a statistical analysis
of measured data. A constant multiplicative mask is derived by averaging spatial errors of a large ...
Characterization of dynamics in RF-MEMS switches

This paper proposes a new method to measure dynamics
and power handling of RF microelectromechanical systems
(MEMS) devices based on a mobile membrane. The method uses
in-phase/quadrature demodulation of an RF signal ...
