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. %K Teoría de la Señal y las Comunicaciones %K Ridged Circular Waveguide %K Dual Mode Filters %K Tuning Screws %K Finite element method (FEM) %~ GOEDOC, SUB GOETTINGEN
