1. A data processing device, comprising:
an internal volume for housing electromagnetic interference (EMI) emitting devices, wherein the EMI emitting devices comprise hardware devices that emit EMI; and
two electromagnetic radiation (EMR) absorbing vents that delineate a gas flow path through the internal volume,
wherein a first EMR absorbing vent of the EMR absorbing vents comprises a first plurality of gas flow paths,
wherein the first plurality of gas flow paths comprises hollow portions of a body that comprises an EMR lossy material,
wherein the first plurality of gas flow paths is delineated by a gas flow pattern on a surface of the body,
wherein a second EMR absorbing vent of the EMR absorbing vents comprises a second plurality of gas flow paths,
wherein the second plurality of gas flow paths is delineated by a non-linear gas flow pattern on a surface of a second body that comprises a second EMR lossy material, and
wherein the lossy material has a real permittivity of a range between 1 and 50 for EMI in a frequency range at least 0.7 and less than 2 gigahertz.
