  1. 1. Frequency Selective Cold-Electron Bolometer Arrays

    Författare :Sumedh Mahashabde; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mm-wave detectors; Cold-Electron Bolometer; Frequency Selective Surface; Focal Plane array; OLIMPO; LSPE;

    Sammanfattning : This work presents the integration of the Cold-Electron Bolometer (CEB) in Frequency Selective Surface (FSS) based arrays targeting balloon-borne telescope missions with high incident power requirements (typically tens of pW). FSS are planar frequency sensitive structures typically consisting of repeating pattern of a simple motif like square, circle, etc. LÄS MER

  3. 2. Direct Write Technology of SIN Tunnel Junctions for Thermometry and Microwave Devices
