Examples of Application (ex.5)Dielectric waveguide coupler - a tutorial example from QW-3D manual Low-permittivity dielectric cross with high-permittivity slab Envelope of vertical E-field at 95 GHz Fundamental mode pattern at 96.7 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 Time-domain electric (above) and magnetic (below) fields revealing location and kind of the discontinuity A strip-line structure terminated with a narrow grounded strip; lower half due to magnetic symmetry condition considered

  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.
