A MICROWAVE EMITTING SYSTEM

摘要

A microwave emitting system (10) which comprises a source of microwaves (20), a longitudinal wave guide (30) connected at a first end (311) to the source such as to receive the microwaves generated thereby and provided with a slot (34) from which the microwaves are irradiated and a short circuit (42) slidably associated to the second end (311) of the wave guide and mobile such as to vary a length of the wave guide (30), characterised in that the short circuit (42) is mobile in alternating motion between a neared and distanced position from the second end of the wave guide (30) continuously and discontinuously during emission of microwaves by the source of microwaves (20).
