Изобретение относитс к СВЧ-энергетике и может использоватьс при нагреве диэлектрических материалов с целью их тепловой обработки .The invention relates to microwave energy and can be used when heating dielectric materials for the purpose of heat treatment.
Известен способ, при котором нагрев материала осуществл етс линейно-пол ризованной электромагнитной волной и эффект дроблени напластованной горной породы зависит от пол ризации волны относительно направлени пластов, причем взрывное дробление камн наблюдаетс лишь в том случае, когда вектор электрического пол ориентирован перпендикул рно к плоскости слоев породыA known method in which the material is heated by a linearly polarized electromagnetic wave and the crushing effect of stratified rock depends on the wave polarization relative to the direction of the strata, and explosive fragmentation of the stone is observed only when the electric field vector is oriented perpendicular to the plane of the layers breeds
1. Однако при этом способе нагрев не контролируетс .1. However, with this method, heating is not controlled.
Наиболее близким техническим решением вл етс способ сверхвысокочастотного нагрева диэлектрических материалов, основанный на облучении материала электромагнитной волной {2.The closest technical solution is the method of microwave heating of dielectric materials, based on the irradiation of the material by the electromagnetic wave {2.
Однако и при этом способе нагрев неравномерен .However, with this method, the heating is uneven.
Цель изобретени - повышение равномерности нагрева.The purpose of the invention is to increase the uniformity of heating.
Дл этого в способе сверхвысокочастотного нагрева диэлектрических материалов, основанном на облучении материала электромагнитной волной, материал облучают электромагнитной волной круговой пол ризации. For this, in the method of microwave heating of dielectric materials based on the irradiation of a material by an electromagnetic wave, the material is irradiated with an electromagnetic wave of circular polarization.
Предлагаемый способ иллюстрируетс чертежом .The proposed method is illustrated in the drawing.
Способ сверхвысокочастотного нагрева заключаетс в следующем.The method of microwave heating is as follows.
Согласно электромагнитной теории слоисто-неоднородна среда с толщиной слоев, малой по сравнению с длиной волны, обладает свойствами одноосного кристалла с оптической осью, перпендикул рной к сло м.According to electromagnetic theory, a layered-inhomogeneous medium with a layer thickness that is small compared to the wavelength, has the properties of a uniaxial crystal with an optical axis perpendicular to the layers.
Выделим из сложной двухкомпонентной слоистой среды два элемента, имеющих взаимно перпендикул рную ориентацию слоев.We distinguish from a complex two-component layered medium two elements having mutually perpendicular orientation of the layers.
Тензор комплексной диэлектрической проницаемости мелкослоистой среды вл етс однократно вырожденным и имеет следующие главные значени :The complex dielectric permittivity tensor of a thin layer medium is singly degenerate and has the following principal values:
g EI - 2(1 + 2) g EI - 2 (1 + 2)
(1) (2) h в2+h2 l(1) (2) h B2 + h2 l
е - J iiiJL 2f2 Л1 + Л,e - J iiiJL 2f2 L1 + L,
где Ej. и е II -соответственно комплексные диэлектрические проницаемости выделенных элементов;where is ej. and e II, respectively, the complex dielectric constant of the selected elements;
81 и 62 - соответственно комплексные диэлектрические проницаемости отдельных слоев двухкомпонентной структуры;81 and 62 are, respectively, the complex dielectric permeabilities of individual layers of a two-component structure;
hi и hz - толщины слоев.hi and hz are the layer thicknesses.
Отсюда видно, что электрофизические параметры элементов слоисто-неоднородногоThis shows that the electrophysical parameters of the elements are layered inhomogeneous
