  1. 6. Design and Performance of Some Components for a Millimeter Wave Imaging Receiver

    Författare :Guillermo F. Delgado Gunckel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nipi MQW; imaging receiver; lens shaping; diplexer; kinoform; opto-electronic quasi-optical modulation; dielectric lenses; sideband filter; diffractive optics;

    Sammanfattning : This thesis deals with the design and performance of some novel devices for an imaging receiver, operating in the frequency band centered at 100 GHz, to be used in radio astronomy research. The emphasis is given on simple, small and reliable devices in order to reduce the complexity of an already complex receiver. LÄS MER
