Attenuation in a circular waveguide with helical corrugation
Abstract
Experimental results of attenuation properties for a circular waveguide with helical corrugation propagating the HE(11) mode are 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.
