Abstract
An electromagnetic interference (EMI) shielding enclosure includes a base having a first threaded lip. A cover has a second threaded lip. The second threaded lip screws onto the first threaded lip and attaches the cover to the base. The base is provided with a first inner recessed wall and the cover is provided with a second inner recessed wall. When the cover is screwed onto the base, the first and second recessed walls form a hollow cavity within the EMI shielding enclosure. The hollow cavity has a curvilinear profile in cross section, such as an ellipsoidal profile, which improves the EMI attenuation characteristics of the EMI shielding enclosure.
