    A complet process of design and measurement of parabolic antennas, is presented. We have implemented a set of programs in order to design and analyze the different geometries of parabolic reflectors. The measurements are ...
  • Cálculo del campo difractado por objetos cilíndricos metálicos o multidieléctricos al incidir sobre ellos una onda 

    Ferrando Bataller, Miquel; Jofre Roca, Lluís (Consejo Superior de Investigaciones Científicas (CSIC), 1986)
    Conference report
    Open Access
    A method is described for calculating the scattered fields from conducting bodies and concentric multilayered cylinders, when they are illuminated by a wave with no z-axis variation. The method is based upon descomposition ...
  • Receptor coherente para imágenes por microondas 

    de los Reyes, Elías; Jofre Roca, Lluís; Ferrando Bataller, Miquel (1984)
    Conference report
    Open Access
    In order to avoid heating in the microwave imaging of biological bodies a very high sensitivity is needed for the receiver. We present a low cost sensitive coherent microwave receiver in microstrip technology.
