    • Integral formulation of the measured equation of invariance: a novel sparse matrix boundary element method 

      Rius Casals, Juan Manuel; Pous Andrés, Rafael; Cardama Aznar, Ángel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1996-05-01)
      Article
      Accés obert
      A novel integral formulation of the measured equation of invariance method is derived from the reciprocity theorem and implemented for perfectly conducting (PEC) 2-D scattering problems. This formulation uses the electric ...

    • Measured equation of invariance: a new concept in field computations 

      Mei, K.K.; Pous Andrés, Rafael; Chen, Z.; Liu, Y.W.; Prouty, M.D. (1994-10)
      Article
      Accés obert
      Numerical computations of frequency domain field problems or elliptical partial differential equations may be based on differential equations or integral equations. The new concept of field computation presented in this ...

    • Modelo sencillo para el estudio de los parámetros de entrada de una antena fractal de Sierpinski

    • Multiband properties of a fractal tree antenna generated by electrochemical deposition 

      Puente Baliarda, Carles; Claret Bonet, Josep; Romeu Robert, Jordi; López-Salvans, M Q; Pous Andrés, Rafael (Institution of Electrical Engineers, 1996-12)
      Article
      Accés obert
      Experimental results on a fractal tree-like antenna are reported. The fractal structure is generated by electrochemical deposition. The antenna presents a multiband behaviour with a denser band distribution than the ...

    • On the behavior of the Sierpinski multiband fractal antenna 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Pous Andrés, Rafael; Cardama Aznar, Ángel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-04-30)
      Article
      Accés obert
      The multiband behavior of the fractal Sierpinski antenna is described. Due to its mainly triangular shape, the antenna is compared to the well-known single-band bow-tie antenna. Both experimental and numerical results show ...

    • Perturbation of the sierpinski antenna to allocate the operating bands 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Bartolomé, R; Pous Andrés, Rafael (Institution of Electrical Engineers, 1996-11)
      Article
      Accés obert
      A scheme for modifying the spacing between the bands of the Sierpinski antenna is introduced. Experimental results of two novel designs of fractal antennas suggest that the fractal structure can be perturbed to enable the ...

    • Small but long koch fractal monopole 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Pous Andrés, Rafael; Ramis, J; Hijazo, A (Institution of Electrical Engineers, 1998-01)
      Article
      Accés obert
      A small but long wire fractal antenna based on the Koch curve is presented. Experimental and numerical results show that the antenna improves the features of a common linear monopole. The radiation resistance is increased ...

    • The cgm and the fdtd for sar studies 

      Pous Andrés, Rafael; Mallorquí Franquet, Jordi Joan; Bayonas, F (Institute of Electrical and Electronics Engineers (IEEE), 1994)
      Text en actes de congrés
      Accés obert
      In the study of electromagnetic radiation effects over dielectric bodies, effective numerical methods are needed. At present, there is a lack of tools for measuring these effects and due to the huge growth of microwave ...

    • The measured equation of invariance and its application to transmission line modelling 

      Pous Andrés, Rafael; Prouty, M.D.; Mei, K.K. (. WORSHOP PROCEEDINGS, 1993)
      Text en actes de congrés
      Accés obert
      The Measured Equation of Invariance (MEI) is a geometry-dependent Finite Difference equation that can be used to terminate a mesh extremely close to the object of interest. The mesh can be terminated much closer than what ...

    • The measured equation of invariance: a new concept in field computation 

      Mei, K.K.; Pous Andrés, Rafael; Chen, Z.; Liu, Y.W. (1992-06)
      Article
      Accés obert
      Computations of electromagnetic fields are based either on differential equations or on integral equations. The differential equation approach using finite difference or finite element methods results in sparse matrices, ...

    • Variations on the fractal Sierpinski antenna flare angle
