    • 3d optical tomography of ferroelectric domains and domain walls 

      Gjaci, Reison (Universitat Politècnica de Catalunya, 2022-09-07)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Kungliga Tekniska högskolan
      In ferroelectric materials, the spontaneous polarization can be reversibly switched by an applied electric field, which makes them attractive for applications in non-volatile memories and other electro-active devices. ...

    • Analysis and Simulation of Distributed Nonlinearities in Ferroelectrics and superconductors for Microwave Applications 

      Seron, David; Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; O'Callaghan Castellà, Juan Manuel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-03-31)
      Article
      Accés obert
      This paper gives closed-form equations for the intermodulation and third harmonic signals generated in a nonlinear transmission line with distributed quadratic nonlinearities in the conductor and dielectric. Although the ...

    • Intermodulation distortion in coupled-resonator filters with nonuniformly distributed nonlinear properties - Use in HTS IMD compensation. 

      Mateu Mateu, Jordi; Booth, James C.; Collado Gómez, Juan Carlos; O'Callaghan Castellà, Juan Manuel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-04-30)
      Article
      Accés obert
      We present a general procedure for calculating intermodulation distortion in coupled-resonator filters that allows one to predict the performance of a nonlinear filter as a function of the general nodal matrix defining the ...

    • Nonlinear dielectric response of BaBi4Ti4O15 ceramics 

      Kumar, Sunil; Ochoa Guerrero, Diego A.; García García, José Eduardo; Varma, K.B.R (2013-02-05)
      Article
      Accés restringit per política de l'editorial
      Nonlinear dielectric response of BaBi 4 Ti 4 O 15 ceramics synthesized via the conventional solid-state reaction route has been monitored over a wide range of electric field strengths (E 0 = 0.5-5 kV/cm). Dielectric ...
