WASP-NET

 

Introduction

WASP-NET’s high optimization efficiency enables engineers to complete design tasks within short design times by direct, fast and accurate overall EM optimization.

A shaped dual-reflector antenna example combined with complete feed network (OMT, taper, horn) can illustrate the impact of this high optimization speed: Desired broadband shape-function specifications can be optimized (ca. 1000 iterations) within less than a day.

 

 

Impact of high optimization speed:  Would one - for illustration purposes - try to optimize this antenna with a more standard method taking e.g. ca. 10 - 30 minutes per frequency point for the whole assembly (antenna + feed-network) instead, the optimization would require ca. 48 - 145 days, which could for m any competitive situations be disadvantageous.

 

Accuracy: Results are full-wave and accurate. WASP-NET’s accuracy can always conveniently be verified by WASP-NET’s own independent cross-check possibilities via different solvers.

 

Accuracy check example: In picture above, when just moving mouse pointer into image field: The picture put underneath shows the independently calculated BOR-FEBI pattern results (cp: green, xp: blue), demonstrating practically identical results with the original BOR-MoM results (upper picture layer).     BOR-FEBI speed: Ca. 76 sec. / fr.

 

 

 

11 sec./fr. = 11 seconds per frequency point (up-to-date i7 HexCore PC)

Antenna optimization example: The optimization of a shaped dual-reflector antenna ~57 lambda 10.7 - 14.5GHz with profiled dielectric support and complete feed-network (OMT, taper, horn) to meet given specs takes in WASP-NET with ca. 1000 iterations and 7 sample points: 1000 x 7 x 11 seconds, i.e. less than a day.

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.
