Compact Broadband Waveguide Filters:
Rectangular waveguides are indispensable components in applications such as radars and satellite communication due to their low loss and high power handling capability.
In applications requiring specified bandwidths, a filtering system capable of producing desired rejection bands while maintaining a low insertion loss must be implemented.
Conventional E-plane waveguide filters involve physical alterations of the waveguide and result in complex and costly structures that are several wavelengths long.
The goal of this project is to use my in situ optimization technique to design compact rectangular waveguide filters that are easy to design and manufacture at a very low cost.
This is achieved through topology optimization of a pixelated metallic patch backed by a dielectric sheet placed along the longitudinal axis of a rectangular waveguide.
The length of the filter is just 3cm.

axis.
