High power millimeter waves are important for industrial processing of dielectric materials. Uniform and homogeneous electromagnetic field distributions within the resonators are desired for controllable production rates. Precise knowledge of the stationary field deposition is therefore essential for microwave oven design and application. The industrial resonators that we are interested in here, make great demands for computer simulation in memory allocation and computational speed, because of the resonator`s dimensions ({approximately} m) compared to the small microwave wavelength ({approximately} mm). This is particularly important in three dimensions, which leads to computationally intensive numerical optimizations using standard schemes for solving Maxwell`s equations, such as Finite Difference-, Finite Element methods etc. Optical approaches promise a much more flexible engineering support for designing and optimizing resonator conditions even on smaller workstations. Investigations and results based on a generalization of Fermat`s principle for wave propagation will be presented and compared to measurements performed on a 30 GHz gyrotron installation.
