    摘要： A microwave resonator for an EPR probehead comprising a metal cavity body (1) supporting an electromagnetic microwave resonance mode having an even number of local maxima of microwave energy, an opening for inserting a sample tube (2) to a center position of the resonator, the center of the opening and the center position of the resonator defining an x-axis, an opening for transmitting microwave radiation into the resonator, two identical dielectric elements (4a,4b) located symmetrically to the E-field nodal plane containing the x-axis and a z-axis perpendicular to the x-axis, is characterized in that each dielectric element is geometrically formed and positioned such that it provides an equal overlap with a local maximum of the microwave electric field energy. Such microwave resonant cavity has thin planar shape for an EPR probehead. The resonator is loaded with two dielectric elements, of identical shape and physical properties, placed symmetrically relative to the central EPR sample. When included in a probehead, this resonator is also contained by the mirror symmetry plane between the main magnet poles.
