radation
Examples of Application (ex.6)A tutorial example of TDR from QW-3D manual
A strip-line structure terminated with a narrow grounded strip; lower half due to magnetic symmetry condition considered
Time-domain electric (above) and magnetic (below) fields revealing location and kind of the discontinuity
Examples of Application (ex.7)Thawing a beefburger in a household oven; QW-3D with QW-BHM
Left: system view
Right: dissipated power patterns through beef and bread, produced by QW-3D under the assumption of constant media parameters at either -20 deg or +20 deg.
Left: temperature-dependent media characteristics automatically considered by QW-BHM option
Right: resulting temperature pattern produced by QW-3D with QW-BHM. Due to thermal runaway effect, after 35 sec. of heating a hot spot is created in bread while beef remains frozen.

What Is QuickWave
QuickWave
is a cutting edge software which
makes possible electromagnetic analysis
and reliable design
without hardware prototyping
What Is QuickWave
Software implemented for the Windows platform, with a user-
friendly interface, including libraries of parameterised designs
What Is QuickWave
A product based on long term original research
conducted by its authors and disseminated
in over one hundred publications
What Makes QuickWave Special
The only EM software for fast 3D design
with no need for 3D drawing!Take a look at our parameterised element libraries further
herein.
The only FDTD software offering fully conformal boundary
models with no need for time-step reduction!
Take a look at our conformal models with clever cell merging. Accuracy improvement with respect to both stair-
case FDTD and brute-force conformal FDTD without cell merging are shown further
QuickWave Features• Conformal meshing and conformal FDTD algorithms • Convenient GUI with libraries of parameterised objects• Extraction of S-parameters, also in multimodal lines
and and below cut-off• Excitation with user-defined source type, pulse type,
available power, delay• Electric, magnetic and metal losses• Extensive display of absolute values of fields & power• Extraction of average dissipated power, also in
multimodal structures• Batch operation, freeze function, multithread options• Interfaces to optimisers for automatic design
