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,
