Orlando (Estados Unidos), 1995.Higher order free space modes can be considered as serious candidates for power millimeter wave transmission in advanced material processing by using medium power CW gyrotrons. These modes can be propagated in a beam waveguide with properly designed mirrors. Here, we present some optimal ways to excite these higher order free space modes from circular symmetric cylindrical waveguide modes by using optimal non linear horn launchers. An original synthesis procedure is proposed which has been successfully tested by computational simulation.2 p.application/pdfengOptimum horn antennasHigher order free space modesBeam waveguidesinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
