TY - JOUR A1 - Álvarez Melcón , Alejandro AU - Molina, Rafael AU - Guglielmi, Marco T1 - Modal Spectrum of the Ridged Circular Waveguide Using the FE Method Y1 - 1994 SN - 0332-1649 UR - http://hdl.handle.net/10317/2415 AB - In this paper, results on the modal spectrum analysis of a Ridged Circular Waveguide (RCW) obtained with the Finite Element Method (FEM) are presented. The results obtained show that the RCW can be used in dual mode filters to eliminate the Tuning Screws unit traditionally required for this kind of hardware.
