Abstract
A low pass filter produced by cable-manufacturing techniques and using a long, distributed capacitance 'filter-line' which, when cut into pieces, produces lumped lossy filters. To exhibit appreciable distributed capacitance together with magnetic flux concentration, use is made of special dielectromagnetic materials based on mixtures which synthesize high permittivity, low permeability and high losses.
