3-D-Printed Dual-Mode Filter Using an Ellipsoidal Cavity With Asymmetric Responses
Enrique López-Oliver, Cristiano Tomassoni
Abstract
A new structure based on an ellipsoidal cavity that operates with the fundamental mode and its degenerate in a transverse routing scheme is presented in this letter. This configuration yields asymmetric filtering functions with two poles and one transmission zero, the position of which can be easily controlled by the rotation of the input and output. For validation purposes, a two-pole filter has been designed and manufactured using 3-D printing techniques. Measured results demonstrate the feasibility of the proposed filter with good agreement between simulation and measurement.
