摘要：

Attenuator-coated helix-support rods in a helical slow-wave structure were modeled by considering them to be made up of lossy dielectric material having equivalent bulk conductivity. The same conductivity values were used in 3D HFSS modeling of the helical slow-wave structure having the helix supported by three such support rods inside a metal envelope, and the attenuation constant of the structure was found. The proposed approach was used to characterize the attenuation constants in the sever region of a typical X-Ku band slow-wave structure and benchmarked against measurement.
