7 Use of the QW-BHM with frequency tuning

This example is available in .../QW-3D/BHM/Heat/heat_tune.QWPro in the QW-Modeller examples directory and can be loaded using File®Open Examples... command from main menu.

General Description

Microwave domestic oven with vertical feed, rectangular shelf, and rectangular food presenting the BHM regime with frequency tuning. The excitation settings automatically include tuning scenario.

Geometry

The oven's inside dimensions are 205 mm, 238 mm, 228 mm in X, Y, Z directions respectively. Its vertical feeding waveguide dimensions are 12 mm, 70 mm, 48 mm in X, Y, Z directions respectively. The rectangular shelf dimensions are 178 mm, 214 mm, 4 mm in X, Y, Z directions respectively. The food dimensions are 101 mm, 120 mm, 24 mm in X, Y, Z directions respectively.
