3 What We Do We invent and commercially develop electromagnetic software packages, of the QuickWave series and apply to electromagnetic research and industrial design

4 What Is QuickWave QuickWave is a cutting edge software which makes possible electromagnetic analysis and reliable design without hardware prototyping

5 QuickWave-3D QW-3D - Our Flagship Product A general-purpose 3D electromagnetic software Includes QW-Editor and QW-Simulator, in a full 3D regime

6 QW-V2D A vector 2D electromagnetic software applicable to the analysis of axisymmetrical devices (antennas-as big as 150 wavelength or more!, resonators, circular waveguide discontinuities). Includes QW-Editor and QW-Simulator, working in a vector 2D regime

7 QW-Editor A graphical editor for definition of geometry, media, I/O parameters and postprocessing. It comprises a library of parameterised objects and a capability for generating further objects and libraries. Conversion to and from CAD formats is also facilitated.

8 QW-Simulator A unique, conformal FDTD solver. Its output data include multi-modal, multi-port S-matrices, radiation and scattering patterns, pattern of field, dissipated power, time-domain reflectometry etc.

9 Areas of Software Application in Industry Telecommunication industry Electronics industry Microwave oven industry Automobile industry Food processing industry Industrial microwave chemistry

10 Areas of Software Application in Science Space and atmosphere research Microwave heating Electromagnetic impact on biological tissues Electronics

11 Examples of Applications (ex. 1.1) WR-10 waveguide quadrature hybrid with six branch lines Design, measurements and QW-3D simulations: S.Srikanth and A. R. Kerr, National Radio Astronomy Observatory, Charlottesville, VA 22903, USA

12 Examples of Applications (ex. 1.2) Amplitude and phase imbalance – from the measured (MS-noisy) and simulated (QWB-smooth) results. (S. Srikanth and A. R. Kerr, National Radio Astronomy Observatory, Charlottesville, VA 22903, USA) For more QW-3D results at NRAO, see: ALMA Memos 381, 343, 325, 278 You will find them at:

13 Examples of Application (ex.2) Design, measurements and QW-3D simulations: T.Schnabel, Zomatch, CA E-plane waveguide diplexer Transmission into higher-frequency (upper) and lower-frequency(lower) channels: measurements simulations

14 Examples of Applications (ex.3) Pyramidal horn antenna Design & measurements: Prof.B.Stec, Technical Military Academy, Poland Simulations: QWED vertical plane measured ____vertical plane simulated horizontal plane measured ____ horizontal plane simulated

15 Examples of Application (ex.4) Axisymmetrical corrugated horn H  at 13.75GHz Radiation patterns at GHz Design & measurements: P.Brachat, IEEE Trans. AP, April 1994 QW-V2D simulations: QWED

16 Examples of Application (ex.5) Dielectric waveguide coupler - a tutorial example from QW-3D manual Low-permittivity dielectric cross with high-permittivity slab Fundamental mode pattern at 96.7 GHz Envelope of vertical E-field at 95 GHz Wide-band S-parameters indicating power loss due to higher modes and /or radation

17 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

18 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.

19 Examples of Application More on microwave heating For more examples of QW-3D application by our users, please refer to the projects run at Worcester Polytechnic Institute and reported at: Comparative Analysis of Commercial Electromagnetic Software You will also find there an independent review of commercial EM software packages:
