Fabrication and characteristics of mesh band-pass filters [PDF]

open access: yesInstruments and Experimental Techniques, 2009
Mesh band-pass filters for 300-, 450-, 600-, and 750-GHz central frequencies are designed and manufactured. Copper and aluminum foil and foil-clad Teflon filters were made by chemical and ionic etching methods, and an aluminum film evaporated on a kapton film was formed by the lift-off lithography method.
