摘要
To prevent interference from secondary electron emission, a base member, as of a waveguide, which in operation is exposed to high frequency electric fields is provided with a coating comprising a rough surface layer having a thickness less than its skin depth, and a further layer of high electrical conductivity between said rough layer and said base member, the thickness of said further layer being substantially larger than its skin depth. The rough layer preferably has a ratio of mean depth to mean pitch of its random corrugations substantially larger than 1:2.
