2. 16. Slot Array Antennas at V-band based on Inverted Microstrip Gap Waveguide

   Author : Jinlin Liu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; inverted microstrip gap waveguide; metallic pins; perfect magnetic conductor; slots array and variational method;

   Abstract : Recently, gap waveguide technology is introduced as a proper guiding structure for millimeter-systems. The conception of gap waveguide technology can be modeled for theoretical analysis by two parallel plates, a top perfect electric conductor layer and a bottom perfect magnetic conductor layer.

4. 17. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining

   Author : Adrian Gomez-Torrent; Joachim Oberhammer; Umer Shah; Goutam Chattopadhyay; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna; orthomode transducer; switch; waveguide; radiofrequency; beamforming network; submillimeter-wave; terahertz; silicon micromachining; deep reactive ion etching; silicon on insulator; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. READ MORE

5. 18. Technology for biocomputational devices based on molecular motors

   Author : Frida Lindberg; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular motors; Nanofabrication; Biocomputation; Nanostructures; Fysicumarkivet A:2019:Lindberg;

   Abstract : For many multivariable problems there are no efficient algorithms for finding solutions. To this day, conventional electronic computers mainly solve problems in a sequential manner. This sequential operation prevents problem-solving within a reasonable time-frame due to superpolynomial, and sometimes even exponential, time complexities. READ MORE

6. 19. Expanding the versatility and functionality of iontronic devices

   Author : Dennis Cherian; Magnus Berggren; Daniel T Simon; Klas Tybrandt; Alon Gorodetsky; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Biological systems rarely use electrons as signal regulators, most of the transport and communication in these system utilize ions. The discovery of conjugated polymers and polyelectrolytes and their unique properties of mixed ionic electronic properties opened the possibility of using these in the domain of bioelectronics, which paved the way for the field of organic bioelectronics.

7. 20. Graphene FET terahertz detectors on flexible substrates

   Author : Xinxin Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensors; THz detectors; flexible electronics; 2D materials; Graphene; field-effect transistors; plastic substrates.;

   Abstract : Terahertz (THz) science and technology have developed rapidly over the past decades, extending the THz application areas from spectroscopy and earth and space sciences to communications, biomedicine and security sensing. Many of these emerging applications require shape-conforming, light-weight and low-cost detectors rather than existing solid-state detection technology. READ MORE
