WASP-NET’s wide application range for accurate, fast EM CAD and optimizations of all kind of passive microwave components / antennas proves - due to WASP-NET’s generality and flexibility - to be practically unlimited.

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 provides full flexibility of 3D solvers combined with high efficiency. Standard building blocks, such as steps and irises etc. are available as catalog elements. WASP-NET is, however, not limited by or restricted to catalog elements. User-defined arbitrary 3D structures or parts thereof are conveniently created in WASP-NET by a user-friendly graphic 3D modeler or by text editors. Geometry parameters are fully parametrized for fast direct EM based optimizations.
Field patterns can be directly optimized including shape profile functions.
3D structures can be exported and, in particular, also be imported using standard formats (e.g. STEP, SAT, BREP, IGES). In this way, imported structures can be de-composed and parametrized for fast optimizations.
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.
