    Abstract : Popular Abstract in Swedish Elektromagnetiska fält finns idag överallt och är en förutsättning för att det moderna samhället ska fungera. Utan att fundera närmare på det, använder vi oss ständigt av de elektromagnetiska fältens förmåga att trådlöst överföra information och energi. READ MORE

  2. 2. Thick Frequency Selective Structures

    University dissertation from Department of Electroscience, Lund University

    Author : Björn Widenberg; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; Elektromagnetism; optik; akustik; optics; Electromagnetism; Energy Saving Window; Radome; Finite Elemente Method; Frequency Selective Structure; Mode Matching Technique;

    Abstract : Popular Abstract in Swedish Denna avhandling presenterar en metod som kan hantera generella tjocka frekvensselektiva strukturer (FSS). Metoden är baserad på modanpassning och finita elementmetoden (FEM). Avhandlingen är en sammanläggningsavhandling och består av en introduktion som följs av fem vetenskapliga artiklar. READ MORE

  3. 3. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Kristin Persson; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

    Abstract : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. READ MORE

  4. 4. Design and Optimization of Wideband Hat-Fed Reflector Antenna with Radome for Satellite Earth Station

    University dissertation from Chalmers University of Technology

    Author : Erik G. Geterud; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna feeds; corrugated surfaces; reflector antennas; optimization; radomes; satellite earth stations.;

    Abstract : This thesis presents the development of a hat-fed refector antenna with radome to be used as satellite earth station. The antenna with self supported feed is relatively compact, circular symmetric and with low cross polarization. To achieve optimum performance over the satellite Ku-band, covering 10.75-14.
