Abstract
An electromagnetic filter includes a filter housing containing a first resonant cavity and a second resonant cavity. Resonators are disposed within each of the cavities. The electromagnetic filter also includes a cavity wall separating the first resonant cavity and the second resonant cavity. The cavity wall includes a T-shaped aperture to achieve magnetic coupling between the first resonant cavity and the second resonant cavity.
