Claim 20:
21. The microwave generator according to claim 18, wherein the at least one transverse bar comprises at least one proximal transverse bar and at least one distal transverse bar parallel and offset from each other along the main axis, wherein the at least one proximal transverse bar and the at least one distal transverse bar are disposed at respective lengths Lprox and Ldist of the short-circuiting element, along the main axis, with:
Lprox=Lc+kprox·Lg/2, wherein kprox is a zero or positive integer;
Ldist=Lc+kdist·Lg/2, wherein kdist is a positive integer greater than kprox;
Lc=p·λg/4;
Lg=λg plus or minus 10 percent;
λg corresponds to the guided wavelength of the microwaves inside of the waveguide, which depends on the dimensions of the waveguide;
p is a correction coefficient less than 1;
so that the at least one proximal transverse bar and the at least one distal transverse bar are offset from each other along the main axis by a spacing EC such that:
EC=Ldist−Lprox=(kdist−kprox)·Lg/2=N·Lg/2 wherein N is a positive integer,
and wherein the at least two coaxial connectors comprise at least one proximal coaxial connector whose conductive antenna is fixed on one of the at least oneproximal transverse bar and at least one distal coaxial connector whose conductive antenna is fixed on one of the at least one transverse bar distal,
and wherein the at least one proximal coaxial connector and the at least one distal coaxial connector are connected to two of the at least two microwave sources operating:
either in phase synchronization if N is even, plus or minus ten degrees;
or in phase shift of 180 degrees if N is odd, plus or minus ten degrees.
