TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The microwaves enter at least one applicator through at least four, preferably eight applicator diffuser matrices. Each of the matrices comprises at least 5, preferably 6 beveled entry channels. The tuner stubs are motor-driven with individual feedback loops to a programmable logic controller assembly which provides continuously-adjustable compensation to match the source of the microwaves to a changing load in the organic-containing material within the applicator. The apparatus further comprises at least two pairs of microwave waveguides, where: each pair of waveguides is split into two by a divaricated waveguide assembly; and each divaricated waveguide assembly has at least one applicator diffuser matrix at the entry point into at least one applicator chamber. In the apparatus: at least one applicator chamber is at least two applicator chambers in communication with each other; and at least two sources of microwaves is at least four sources of microwaves. The apparatus comprises: at least two pair of microwave waveguides of unequal length, where each waveguide is in communication with a source of microwaves and the applicator chamber; and at least one applicator diffuser matrix at an entry port into at least one applicator chamber from each of at least two pair of microwave waveguides. The applicator diffuser matrix comprises a sealed, dual-flanged waveguide isolation assembly between the microwave diffuser and the applicator input port which includes two low-loss, dielectric wafers inset within a flange of the isolation assembly. The applicator is a sealed, purged low-loss seamless aluminum cavity. The waveguide isolation assembly is nitrogen-filled to maintain an inert, non-flammable atmosphere within the assembly.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process further comprises monitoring a load in the organic-containing material with the applicator and using at least one tuning stub to match a load/tuner combination. The step of monitoring comprises: a four-stage automated tuner assembly having four tuner stubs, in which the tuning stubs match the load/tuner combination. The step of matching is achieved by controlling an amplitude of a reflection coefficient of the organic-containing material by varying an insertion depth and a diameter of the tuning slug, where a middle pair of tuning stubs are separated by 3/8 waveguide wavelength and each of an outer pair of tuning stubs are separated by 1/4 waveguide wavelength.
