Parabolic Torus Reflector Antenna

WIPL-D Pro is well-established full wave 3D EM solver based on state-of-the-art MoM. MoM is inherently suitable for radiating problems and simulation of electrically moderate and large structures. A typical example are reflector antennas, with diameters measured in tens or hundreds of wavelengths.

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. TRA does not offer excellent aperture efficiency as parabolic reflector.If illuminated with several fixed antennas, it offers an efficient multi-beam operation.

By using anti-symmetry and asymmetry, the number of unknowns is reduced 4 times (less than 25,000 unknowns). Reflector aperture is ~1.8×3 m (60×100 lambda). The kernel runs twice at standard desktop PC. Entire simulation time is measured in minutes and can be additionally speed up by using low-end Nvidia GPU card.
