Abstract
An electro-magnetic wave filtering and impeding board is made of metal and includes a first side and a second side. The first side has multiple linear slots and the second side includes multiple concaved geometric holes which communicate with the linear slots. The electro-magnetic waves are impeded by the metallic material and weakened when passing through the linear slots and the geometric holes so as to impede the electro-magnetic waves.
