  • DC field induced antiferroelectric phase transition in bulk, single crystal strontium titanate

    • Dielectric hysteresis in bulk, single crystal SrTiO3 (STO) with YBa2Cu3O7. x(YBCO) electrodes is studied experimentally at 77K. In contrast with previously reported experiments [1], [2] the antiferroelectric phase transition is observed at higher temperature (i.e. 77K). The phase transition is observed where the crystal is cooled either with short circuited or with open circuited electrodes. The phase transition does not result in detectable changes in the microwave losses.

  • Effects of package width on K-band high-temperature superconducting filters
  • 1995
  • Ingår i: Microwave and Optical Technology Letters. - : Wiley. - 1098-2760 .- 0895-2477. ; 10:6, s. 315-317
  • Tidskriftsartikel (refereegranskat)abstract
    • The effect of substrate/package width on filter performance is demonstrated and discussed for 18-GHz packaged filters using high-temperature superconducting (HTS), coupled microstrip lines. The filters are made of 0.3-μm YBa2Cu3O7 – ∂8 (YBCO) on MgO substrates with copper ground planes. The HTS filter shows a minimum insertion loss (IL) of 0.9 dB, steep skirts, and very good out-of-band rejection (> 45 dB up to 21 GHz) at 77 K with a bandwidth of 2.8% and a 0.3-dB ripple

  • Mode chart of electrically thin parallel-plate circular resonators
  • 2001
  • Ingår i: IEE Proceedings: Microwaves, Antennas and Propagation. - : Institution of Engineering and Technology (IET). - 1350-2417 .- 1359-706X. ; 148:1, s. 51 - 55
  • Tidskriftsartikel (refereegranskat)abstract
    • Modes in electrically thin circular parallel-plate resonators are discussed in detail. It is shown that the widely used mode indices (found from the field solutions) do not indicate the radial numbers of the field maximums in a straightforward manner. The diameter of the disc, not the radius, accommodates integer numbers of the field maximums (antinodes). These diametrical numbers are expressed in terms of radial mode indices. Emphasis is placed on the first axially symmetric mode TM020, which was incorrectly regarded as TM010 in the past. Some applications of the mode chart, including interpretation of experimental observations, are also discussed. Comparison is made with microstrip and annular resonators.

  • A General Statistical Equivalent-Circuit-Based De-Embedding Procedure for High-Frequency Measurements
  • 2008
  • Ingår i: IEEE Transactions on Microwave Theory and Techniques. - 0018-9480 .- 1557-9670. ; 56:12, s. 2692-2700
  • Tidskriftsartikel (refereegranskat)abstract
    • A general equivalent-circuit-based method for the de-embedding of scattering parameters is presented. An equivalent circuit representation is used to model the embedding package. The parameters in the models are estimated with a statistical method using measured data from all de-embedding standards jointly together. Hence, it is possible to assess parameter estimates and their variance and covariance due to measurement uncertainties. A general de-embedding equation, which is valid for any five-port with a defined nodal admittance matrix, is derived and used in the subsequent de-embedding of measured device data. Different equivalent circuit models for the embedding network are then studied, and tradeoffs between model complexity and uncertainty are evaluated. Furthermore, the influence of varying number and combinations of de-embedding standards on the parameter estimates is investigated. The method is verified, using both measured and synthetic data, and compared against previously published work. It is found to be more general while keeping or improving accuracy.

  • Clinical Diagnostics and Treatment with Electromagnetic Fields
  • 2010
  • Ingår i: 4th European Conference on Antennas and Propagation, EuCAP 2010; Barcelona; Spain; 12 April 2010 through 16 April 2010. - 9788476534724 ; , s. C15P2-1
  • Konferensbidrag (refereegranskat)abstract
    • There is a need for novel diagnostic and treatment systems to overcome the limitations with todays modalities. Microwave and THz based system has the potential to become both sensitive and specific in several applications. In this paper we discuss several applications that are currently being developed at the Chalmers University of Technology.
