TRA does not offer excellent aperture efficiency as parabolic reflector.If illuminated with several fixed antennas, it offers an efficient multi-beam operation.īy using anti-symmetry and asymmetry, the number of unknowns is reduced 4 times (less than 25,000 unknowns). Unique features allow WIPL-D to be unbeatable tool for full wave simulation of electrically large reflectors: quadrilateral mesh, HOBFs, efficient parallelization on multi-core CPU and support for inexpensive GPU cards, built-in reflector pre-meshed primitive. Torus reflector antenna (TRA) is a quasi-parabolic antenna, where the parabola is rotated around an axis which stands vertically to main transmission axis. A typical example are reflector antennas, with diameters measured in tens or hundreds of wavelengths. MoM is inherently suitable for radiating problems and simulation of electrically moderate and large structures. WIPL-D Pro is well-established full wave 3D EM solver based on state-of-the-art MoM.
