A stripline conductor is sandwiched between two ferrite slabs which, in turn, are sandwiched between two magnetic pole pieces. The pole pieces are in contact with opposite poles of a permanent magnet, placing the ferrite slabs in a magnetic field. The distance between the pole pieces varies along the length of the stripline, causing the magnetic field to be nonuniform. The ferrite slabs will absorb electromagnetic radiation at a frequency determined by the magnetic field strength and thus signals on the stripline will be absorbed in a frequency band determined by the range of magnetic field strengths along the length of the stripline.
