    • A device for microwave treatment of materials includes a mold (1) used to hold the material (3) to be treated and a microwave generator which is used to apply to the mold (1) the microwave energy necessary for treatment of the material. The mold includes at least two dielectric materials (4,5,6,7) surrounding the material (3) to be treated. The dielectric materials have dielectric permittivities which differ so that the attenuation of one elementary segment of length l located between the points of side z(n-1) and zn of the longitudinal dimension of the material (3) to be treated which includes at least one section broken up into segments of length l, is controlled by the relationship: ##EQU1## in which: .alpha. is the attenuation in the elementary segment in question,.alpha.o is the initial attenuation in the body of the section which includes the elementary segment in question,Po is the microwave power applied to the section, P(n-1) is the microwave power transmitted in the plane of side z(n-1).
    • 用于微波处理材料的装置包括用于保持待处理材料(3)的模具(1)和用于向模具(1)施加用于处理材料所需的微波能量的微波发生器。 模具包括围绕待处理材料(3)的至少两个电介质材料(4,5,6,7)。 电介质材料具有不同的介电介电常数,使得长度为1的一个基本段的衰减位于要处理的材料(3)的纵向尺寸的z(n-1)面和zn侧的点之间,其至少包括 分为长度l的段的一个部分由以下关系控制:其中:α是所讨论的基本段中的衰减,αo是包括基本段的部分的体内的初始衰减 在这个问题上,Po是施加到该部分的微波功率,P(n-1)是在z(n-1)侧的平面中传输的微波功率。
