| Abstract: | Experimental results of attenuation properties for a circular waveguide with helical corrugation propagating the HE 11 mode is presented. Dispersion curve and attenuation values are obtained using classical cavity measurements. First results show a low attenuation and then such a structure would be convenient for antenna feeder applications. |
