Hybrid Multi-Solver Domain Decomposition Electromagnetic CAD and Optimization Technology

What is WASP-NET?

WASP-NET®, the Waveguide and Antenna Synthesis Program for NETworks, has been created to help you get extraordinary time-saving benefits for your professional electromagnetic (EM) CAD designs and optimizations while not compromising full-wave accuracy and general 3D structure flexibility

High design efficiency and fast product output are increasingly mission-critical for today’s microwave, antenna, space and communication industries. The hybrid EM CAD and optimization tool WASP-NET helps reduce time to market through extremely high simulation and optimization efficiency and accuracy.

WASP-NET’s high optimization efficiency enables engineers to complete design tasks quickly through direct, fast and accurate full-wave overall EM optimization. The simulation speed of WASP-NET enables full design space exploration through a high number of optimization iterations in a short time. In this way, extremely challenging design problems can be solved quickly.

WASP-NET’s hybrid multi-solver technology uniquely combines mode-matching (MM) speed with finite-element (FE) flexibility and method-of-moment (MoM) radiation computation efficiency, accelerated by domain-decomposition method (DDM), fast multipole method (FMM), adaptive integral method (AIM), adaptive cross-evaluation (ACE), iterative physical optics (IPO), and physical theory of diffraction (PTD).

Benefits for users are extremely high calculation speed, complete 3D structure flexibility and full-wave accuracy for efficiently optimizing all passive microwave components, antennas and arrays, including feed-networks, directly on rigorous EM level. WASP-NET has been acknowledged by market leaders worldwide for over 25 years for solving challenging EM design problems with fast optimizations.

WASP-NET Applications

KA Band Ortho Mode Transducer

Waveguide Structures

Waveguide components, such as filters, couplers, diplexers, multiplexers, polarizers, ortho-mode transducers (OMTs), dielectic resonators, and circulators can very efficiently be designed and optimized by using WASP-NET, because large portions of the waveguide structures can be processed by the quasi-analytical mode-matching (MM) technique and 3D EM can be limited to those parts, which MM cannot handle.

Antennas Including Feed Networks

For radiating elements, WASP-NET utilizes the method-of-moments (MoM) in form of the most advanced algorithms, such as the adaptive integral method (AIM), the multilevel fast multipole method (MLFMM), and the domain decomposition method (DDM).

Complete feed-networks (such as OMTs, polarizers, etc.) can directly be integrated in the antenna design and optimization process achieving the optimum overall performance and unprecedented accuracy in a minimum of time.

Antenna Arrays

WASP-NET includes a powerful array tool, which allows analyzing and optimizing antenna arrays both with the fast Floquet mode algorithm (infinite array extension, “periodic boundary”) and the rigorous domain-decomposition method (DDM), which takes the finite extension of the array rigorously into account.
