4. 2. Optical Analysis and Characterisation of the Climate Research Instrument STEAMR

   Author : Arvid Hammar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limb viewing; Monte Carlo; Stratosphere-Troposphere Exchange And climate Monitor Radiometer STEAMR ; quasi optics; THz; antennas; multi-beam; tolerance analysis; submillimeter-wave instruments; radiometers;

   Abstract : A growing interest for making high resolution observations in the upper troposphere and lower stratosphere has motivated the development of the multi-beam satellite-borne instrument Stratosphere-Troposphere Exchange And climate Monitor Radiometer (STEAMR). The measurements made by STEAMR will be used to monitor trace-gases and link the occurence of these to the Earth's climate by accurate modeling of the atmosphere. READ MORE

5. 3. Silicon micromachined waveguide components for terahertz systems

   Author : Bernhard Beuerle; Joachim Oberhammer; Umer Shah; Kamal Sarabandi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micromachining; waveguide; terahertz; deep reactive ion etching; silicon on insulator; on-wafer characterization; InP; SiGe; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents silicon micromachined waveguide components for sub-terahertz and terahertz (THz) systems fabricated by deep reactive ion etching (DRIE). Historically the main driving force for the development of THz systems has been space-based scientific instruments for astrophysics, planetary and Earth science missions. READ MORE

6. 4. Reconfigurable On-Chip Instrument Access Networks : Analysis, Design, Operation, and Application

   Author : Farrokh Ghani Zadegan; Integrerade elektroniksystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-chip instruments; reconfigurable networks; access time optimization; retargeting; fault management;

   Abstract : The constant need for higher performance and more advanced functionality has made the design and manufacturing of modern electronic chips highly demanding. Moreover, the use of smaller transistors in modern chips has increased their sensitivity to aging and faults, hence the need to constantly monitor the correct operation of these chips. READ MORE
