In this study, a symmetric waveguide bandpass filter is proposed using a systematic design process. The waveguide device is designed to control the operation frequency range by changing the metallic barrier width in the system and the finite element method is employed for numerical analysis. We used topology optimization based on the On/Off method for initial concept design with the design objective to maximize the transmitted electric intensity at the target frequency. Detail two-dimensional metallic structure for a tunable bandpass filter was determined through successive parametric studies using the shape primitively derived from the On/Off method. The performance of the proposed waveguide system was verified by numerical simulations and experimental measurements.
