2. 1. Optimal Near-field Antenna Apertures in Lossy Media

   Author : Aidin Razavi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal near-field aperture; near-field focusing; near-field antennas; near-field power transfer; array signal processing.; maximum penetration;

   Abstract : Antennas are traditionally designed for far-field applications such as wireless communications, radar, etc., where the antenna systems interact with other systems and objects which are located in the far-field zone of the antennas. READ MORE

4. 2. Characterization and Design Requirements for Antennas in the Near-field and the Random-LOS Propagation Environment

   Author : Aidin Razavi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization-MIMO; Random-LOS; OTA; Antenna measurements; near-field antennas; antenna characterization; MIMO; near-field focusing;

   Abstract : The choice of antenna for a particular application depends on the requirements imposed by that application. These can be, the application's field region (i.e., near-field or far-field), polarization, radiation pattern, radiation efficiency, system throughput, etc. READ MORE

5. 3. Probing nanoscale phenomena with nanoplasmonic sensors

   Author : Francesco Mazzotta; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; Nanopores; Localized surface plasmon resonance; Biosensor; Catalysis; Nanoplasmonics; Nanodisks; Nanofabrication;

   Abstract : The development of the modern society is strongly influenced by the improved possibility to integrate sensing technology into traditional devices. The development of smaller, more efficient and integrated sensors have already transformed traditional business areas, such as healthcare with the introduction of e-health and portable diagnostics.

6. 4. Parametrically pumped superconducting circuits

   Author : Philip Krantz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SQUID; circuit quantum electrodynamics; Josephson junction; Superconducting circuits; resonators; parametric oscillators; quantum bit; pumpistor; quantum information;

   Abstract : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).

7. 5. Studies On Design of Near-Field Wireless-Powered Biphase Implantable Stimulators

   Author : Yonatan Habteslassie Kifle; Jacob Wikner; Atila Alvandpour; Sebastian Bader; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Portable and implantable electronics are becoming increasingly important in the healthcare sector. One of the challenges is to guarantee stable systems for longer periods of time. If we consider applications such as electrical nerve stimulation or implanted ion pumps, the requirements for, e.g. READ MORE
