  3. 7. Moment Method Analysis of Antennas in Reverberation Chambers and Cylindrical Structures

    Författare :Ulf Carlberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cavity; spectral domain method; cylindrical structure; Ewald summation; Green s function; absorption cross section; moment method; reverberation chamber; antenna;

    Sammanfattning : This thesis is a collection of papers using the method of moments for numerical analysis. The papers can be divided into two main groups; a study of antennas in reverberationchambers, and a study of antennas in cylindrical structures.The reverberation chamber is a metal cavity for measuring antennas and other devices.

  5. 9. Dynamic Equations foe Spherical and Cylindrical Shells Using Power Series Method

    Författare :Reza Okhovat; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power series.; surface differential operators; shell equations; eigenfrequency; anisotropy; Spherical shell; cylindrical shell; dynamics;

    Sammanfattning : Shells are commonly used in many branches of engineeringand have therefore beeninvestigated for a number of different types of shells.A shell can be considered as a curved plate having small thickness compared to the other geometrical dimensions as well as to the wavelengths of importance.
