1. 1. Efficient Calculations of Two-Dimensional Radar Cross-Section Using DGFEM

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Daniel Persson; [2020]
   Nyckelord :numerical methods; DGFEM; discontinuous Galerkin; finite element method;

   Sammanfattning : A two-dimensional discontinuous Galerkin finite element method algorithm in the time domain was developed for calculation of the radar cross-section of an arbitrary object. The algorithm was formed using local nodal basis functions in each element and coupling them via numerical upwind flux. LÄS MER

3. 2. Performance Comparison Between FEM and DG with Application in Electromagnetics

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Oscar Möller; [2016]
   Nyckelord :DGFEM; FEM;

   Sammanfattning : Military aircraft have strict requirements to show a low radar signature within different aspect angels and frequency bands. The Finite Difference method and Finite Element method are used by Saab to determine the radar signature from different objects, but the methods  suffer from a few limitations. LÄS MER
