    Abstract : In this research new RF/microwave-based sensor solutions were developed for the monitoring of biological cells and human beings to obtain a better understanding of their activity or state in a quick, cheap, easy and continuous way. The effect of different substances on cell behaviour can be monitored by measuring the electrical environment where changes are observed as cells react to a stimulus. READ MORE

  4. 2. Processing and On-Wafer Test of Ferroelectric Film Microwave Varactors

    Author : Jang-Yong Kim; Alexander Grishin; Dag Winkler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : ferroelectrics; sodium potassium niobates; silver tantalite niobate; barium strontium titanate; thin films; pulsed laser deposition; rf magnetron sputtering; coplanar waveguide; photolithography; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Microwave materials have been widely used in a variety of applications ranging from communication devices to military satellite services, and the study of materials properties at microwave frequencies and the development of functional microwave materials have always been among the most active areas in solid-state physics, materials science, electrical and electronic engineering. In recent years, the increasing requirements for the development of high speed, high frequency circuits and systems require complete understanding of the properties of materials function at microwave frequencies.

  5. 3. MM-wave integrated RF-MEMS tunable cavity resonators, filters and ultra-low phase-noise oscillators

    Author : Dragos Dancila; Isabelle Huynen; Universite catholique de Louvain (UCL); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Within the Microelectronics Industry, the core research is focused on the realization of the Moore's law, which states that circuit density doubles every 24 months, shaping the framework of the More of Moore paradigm. However, Moore's law is expected to end, as devices are reaching limitations inherent to the approach of the atomical dimensions. READ MORE

  6. 4. Sub-micron Structures in Laser Ablated YBa2Cu3O7-x Thin Films

    Author : Peter Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis treats the epitaxial growth of high-Tc superconductors and other perovskite oxides as well as the patterning of these into sub-micron structures for superconducting electronic devices. A computer controlled laser ablation system, based on a KrF excimer laser (248 nm) to induce ablation, was developed to allow complex thin film growth processes. READ MORE
