OVEN FOR MICROWAVE HEATING OF LONG DIELECTRIC PRODUCTS Russian patent published in 1996 - IPC

FIELD: microwave devices. SUBSTANCE: device has first waveguide for input of microwaves and second waveguide, where heated dielectric product is located. Both waveguides have common wall, where coupling units are located. Coupling units are designed as grid of metal conductors. Grid transparency for microwave electromagnetic field increases from at most 0.1 to at least 0.2 factor. Lowest factor of transparency is in point where microwaves are entered, greatest factor of transparency is in point where microwaves are output. Transparency factor depends on equation given in invention specification. EFFECT: increased functional capabilities. 4 dwg
