    • An apparatus providing uniform microwave processing of products especially those that are likely to absorb microwave energy such as meat and the like. The apparatus uses at least a pair of complimentary processing waveguides. The waveguides are offset along at least one axis thereof so that the energy coupled to the product when traveling through a first waveguide section is presented with a complimentary or mirror image of the field variation applied to the product when traveling in the second waveguide. Energy may be fed to the elongated waveguides through a broad open wall or a wall having narrow openings. Coupling values can therefore be adjusted to transfer a higher percentage of energy in the feeder waveguide as microwaves propagate but then are diminished by a previous coupling section.
    • 一种提供产品的均匀微波加工的装置,特别是那些可能吸收微波能量如肉等的微波处理装置。 该装置使用至少一对互补处理波导。 波导沿着其至少一个轴线偏移,使得当行进通过第一波导部分时耦合到产品的能量呈现当在第二波导中行进时应用于产品的场变化的补偿或镜像。 可以通过宽敞的开放壁或具有窄开口的壁将能量馈送到细长波导。 因此,可以调节耦合值,以在微波传播时在馈线波导中传输较高百分比的能量,但随后由先前的耦合部分减小。

    • An apparatus, system, and method, for using circular mode magnetic microwave energy to heat the product in a continuous microwave process. The microwaves are generated and transmitted as rectangular waveguide mode microwave energy, and are converted by mode converters to circular magnetic mode microwave energy. As circular magnetic mode microwave energy, the microwave energy passes through a material and is reflected on the other side back into the material, thus traveling through the material a second time. Reflected microwave energy from the main reflected wave as well as reflections from other structures, surfaces and layers in the system travel back toward the microwave source. They are sensed, and a computer tuning system causes capacitive probes to generate offsetting microwave reflections, which are opposite in phase and equal in magnitude to the sum of all of the reflected waves. These induced reflections cancel and negate the reflected microwaves, resulting in optimum utilization of microwave energy to heat the product.
    • 一种在连续微波过程中使用圆形磁微波能量加热产品的装置,系统和方法。 微波产生并传输为矩形波导模式微波能量,并由模式转换器转换为圆形磁模式微波能量。 作为圆形磁模微波能量,微波能量通过材料并在另一侧反射回材料,从而再次穿过材料。 来自主反射波的反射微波能量以及系统中其他结构,表面和层的反射回到微波源。 它们被感测到,并且计算机调谐系统使得电容探针产生相位相反的偏移微波反射,并且在幅度上与所有反射波的和相等。 这些诱导的反射抵消和否定反射的微波,从而最佳地利用微波能量来加热产品。

    • A microwave energy applicator radiating uniformly all around the applicator that maintains high efficiency Voltage Standing Wave Ratio (V.S.W.R.) for surrounding media of dielectric constants varying from about 1 to about 80. In a particular embodiment, the high efficiency V.S.W.R. is less than about 1.3:1. The applicator can include a circular polarizer connectable to a dielectric waveguide radiator. The radiator can be substantially solid and include a substantially circular outer cross-section that tapers to an end. In one embodiment, the radiator includes a conical void formed in a dielectric entry section.
