Application Study of New Solid-State High-Power Microwave Sources for Efficiency Improvement of Commercial Domestic Ovens

The work is concerned with an emerging technology of microwave ovens fed by several independently controlled solid state power sources. Its advantages are summarized and a computational method for adjusting individual amplitudes, positions, and relative phases of the multiple sources is presented in general terms. While mathematical details will be published elsewhere, here for the first time the optimization algorithm is applied to a commercially available domestic oven cavity. To this end, it has already been linked to one popular commercial software package but benefits are predicted for the modeling community as a whole, helping its products gain in adequacy for microwave heating applications. With a soon expected advent of economically affordable semiconductor high-power amplifiers, the proposed multi-source optimization technique will pave the way towards "green" domestic ovens with energy consumption reduced by up to 25%, enriched functionalities, and enhanced safety of foods prepared in a fully controlled environment. It is thus relevant to microwave oven designers, microwavable food manufactures, and thereby to the society The target audience for this presentation is broad and encompasses both newcomers and pioneering specialists in the field of solid state sources for microwave processing.
