Abstract
A floating microwave filter in a waveguide structure comprises filtering elements sandwiched between two foam half-bars that are placed inside a waveguide. The filtering elements are metal features etched in the surface of one of the two foam half-bars and the waveguide is an internally hollowed-out block of foam having a metallized external surface.
