Abstract:
A microwave resonator for high-temperature treatment of materials, comprising: a resonator housing having a longitudinal axis and a symmetrical interior shape of a prism with an even-numbered polygonal cross-section, said resonator housing comprising planar side wall segments having side edges and end edges and being joined along their side edges and planar end walls joined to said side wall segments at the end edges thereof, one of said end walls having a microwave in-coupling window disposed near one of said side edges and forming a beam path with an axis which is inclined with respect to the longitudinal housing axis at an acute angle and which is directed toward said one side edge between the two planar side wall segments forming said edge closest to the in-coupling window such that a divergent microwave beam entering said resonator along said beam path axis is divided, upon its first reflection, into two symmetrical beam components directed toward the other end wall and being reflected in a further fanning fashion by said other end wall, thereby providing, with all the successive reflections, for an essentially homogenous field distribution throughout the whole resonator volume.
