PENETRATION WAVEGUIDE FOR BROADBAND ELECTROMAGNETIC ATTENUATION

摘要

The present invention relates to a penetration waveguide and, more specifically, to a penetration waveguide for broadband electromagnetic attenuation, which is formed in an electromagnetic wave shielding structure having computation and communication equipment so that multiple optical cables connected to the computation and communication equipment can be inserted into the electromagnetic wave shielding structure; and prevents electromagnetic waves generated in an external equipment from flowing into the electromagnetic wave shielding structure through the penetration waveguide. Thereby, the present invention comprises a penetration waveguide which is composed of a conductor and has a hollow, and an electromagnetic wave absorption member formed on the inner wall surface of the hollow.
