Fast EM CAD and optimization of lens antennas including feeds

• Fast CAD and optimization of all kind of antenna structures with lenses + feed-networks. Such as: •Corrugated horns with lenses, •Horns with dielectric covers, •Aperture antennas with metal lenses •User-defined arbitrary shaped lenses, etc.

• Rigorous Inclusion of feed-networks, such as polarizers, OMTs, filters, tapers, etc.

• WASP-NET internal cross-check verification by independent different solvers

• Convenient user-friendly design by wizards: Horn-wizard, single- / dual- reflector antenna wizard

• Convenient user-friendly Designer Data Base with fully optimized ready to use design examples, which can be scaled to desired frequencies, modified and re-optimized to desired specifications

WASP-NET utilizes for radiating structure parts the rigorous method-of-moments (MoM) in all advanced fast MoM-algorithm forms. WASP-NET’s powerful and general hybrid EM CAD engine goes also in this way far beyond applying approximate methods for apertures, such as spherical mode-expansions.
WASP-NET’s pioneering efficient hybrid multi-solver EM CAD engine involves all proven solvers (MM / MoM / FEM / FD / FE-BI / PTD / PO / SBR-PTD). WASP-NET utilizes automatically the most efficient solver for appropriate sub-parts of a structure. This unique hybrid combination of solvers for calculating microwave structures achieves high EM CAD optimization speed while maintaining full-wave EM accuracy as well as full 3D generality and flexibility.
WASP-NET’s EM CAD engine needs for the rigorous calculation of antenna components merely a couple of seconds up to some tens of seconds on state-of-the-art PCs. Shown speed benchmarks (per frequency point (fr.)) demonstrate WASP-NET’s high efficiency. Highest possible speed is particularly important when optimizing structures.
