Abstract
Disclosed are devices for shielding one or more connection ports from electromagnetic interference emissions. In one embodiment, the device includes a conformal member having a proximal aperture, a distal aperture, and a channel extending therethrough. The distal aperture has a maximum cross-sectional dimension that is less than about one half of a cutoff wavelength, thereby forming a waveguide for attenuating EMI signals that have a wavelength greater than a predetermined cutoff wavelength. In another embodiment, the conformable member includes first conformable element and a second conformable element. The conformable elements, when mated, form a proximal aperture, a distal aperture, and a channel extending therethrough having substantially the dimensional characteristics described above.
