bread, produced by QW3D 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

Offset metal boundary creating a small cell:
1. Stair-case - neglect small cell
2. Brute force conformal - leave small cell, reduce time step
3. Advanced conformal - merge cells
