ABSTRACT:
A data processing system and housing are disclosed having reduced electromagnetic energy emissions. A central processor is mounted within a generally rectangular conductive outer case which includes one or more apertures for receiving and mounting electronic subassemblies such as: diskette drives; fixed disk drives; tape drives; and, optical disk readers. A conductive waveguide assembly having at least one waveguide is then mounted within the conductive outer case with one end of the waveguide mated conductively to the aperture within the conductive outer case. Electromagnetic energy from the electronic subassembly or from within the conductive outer case must then traverse the conductive waveguide prior to emission from the data processing system housing through the aperture therein. The shielding effect of requiring electromagnetic emissions to traverse an internal waveguide will provide substantial attenuation of electromagnetic interference.
