  2. 1. Design Space Exploration of Digital Circuits for Ultra-low Energy Dissipation

    Author : Syed Muhammad Yasser Sherazi; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; ultra low-voltage; ultra low-energy; subthreshold sub-VT ; body biasing; pipelining; unfolding; half-band digital filter.;

    Abstract : The ever expanding market of ultra portable electronic products is compelling the designer to invest major efforts in the development of small and low energy electronic devices. The driving force and benefactors of such devices are (but not limited to) e-health system, sensor network applications, security systems, environmental applications, and home automation systems.

  4. 2. Ultra-wideband Antenna and Radio Front-end Systems

    Author : Magnus Karlsson; Anders Rydberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communication; ultra-wideband; radio communication; UWB bandwidth; antenna parallelism; Electrical engineering; Elektroteknik;

    Abstract : The number of wireless communication applications increase steadily, leading to the competition for currently allocated frequency bands. Pressure on authorities around the world to permit communications in higher and wider frequency ranges to achieve higher wireless capacity than those existed in the past has resulted in several new specifications.

  5. 3. Ultra wideband microwave hyperthermia for brain cancer treatment

    Author : Massimiliano Zanoli; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultra wideband; treatment planning; brain cancer; applicator design; time reversal; microwave hyperthermia;

    Abstract : Despite numerous clinical trials demonstrating that microwave hyperthermia is a powerful adjuvant modality in the treatment of cancers, there have been few instances where this method has been applied to brain tumors. The reason is a combination of anatomical and physiological factors in this site that require an extra degree of accuracy and precision in the thermal dose delivery. READ MORE

  6. 4. EM Design for New Ultra Wide Band Technologies: Eleven Feed Baluns, Bowtie Antennas and Gap Waveguides

    Author : Syed Hasan Raza Zaidi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-wideband; Eleven feed; gap waveguide; baluns; Multiport feeding network; power divider; ring hybrid.; packaging;

    Abstract : UWB (ultra wideband), depending on the application requirement, is usually referred to more than 500 MHz bandwidth for radio/wireless applications. Here in this thesis it is also used to denote extremely wideband antennas and components of several octaves bandwidth, particularly for high frequency applications. READ MORE
