Abstract
A device for microwave heating, including a wave guide, in which a material is intended to be heated, and a microwave source connected to the wave guide. The wave guide includes a portion wherein its cross-sectional area decreases continuously from the end of that portion located closest to the microwave source to the other end of the portion part, and along that portion the wave guide includes a portion with a geometry, at which fed-in microwave energy no longer can propagate in the wave guide, i.e., the wave guide proceeds continuously to so-called cut off at a certain distance from the narrower end of the part.
