Abstract:
1. A microwave generator, comprising a housing having two mutually opposite electrodes which are separated via an electrode intermediate space which is filled with a first dielectric, said electrodes having a spark gap therebetween, which breaks down in order to emit microwaves upon the application of a high voltage, wherein the electrode intermediate space ( 13 , 13 a , 13 b ) is at least partially filled with a second dielectric ( 15 , 15 a , 15 b ) which has a different dielectric constant in comparison with that of the first dielectric ( 14 , 14 a , 14 b ) which is located between the electrodes ( 6 , 7 ) in order to vary the microwave frequency, said second dielectric ( 15 , 15 a , 15 b ) being retained in a first reservoir ( 17 , 17 a , 17 b ) which communicates with the electrode intermediate space ( 13 , 13 a , 13 b ).
