Mechanically Reconfigurable Waveguide Filter Based on Glide Symmetry at Millimetre-Wave Bands

open access: yesSensors, 2022
This paper presents the design and fabrication of a mechanically reconfigurable filter at W band based on the concept of glide symmetry. The tunability is achieved by breaking and regenerating the glide symmetry.

Double-split labyrinth resonator with defective ground system for wide-band band-stop filter application

open access: yesAIP Advances, 2018
A labyrinth resonator with defective ground structure (DGS) is introduced for designing a wide-band band-stop filter in order to adjust the resonating characteristics by varying the dimension of the structure to cover 2.75 – 10.30 GHz.

Lightning attachment procedure optimization algorithm for optimal design of digital FIR band stop filter

open access: yesMeasurement: Sensors, 2022
This study uses the Lightning Attachment Procedure Optimization (LAPO) method to show how to design a digital finite impulse response (FIR) 20th order band stop filter (BSF). LAPO is a physical-based metaheuristic optimization algorithm.
