Abstract
Theoretical and experimental work on tunable bandstop filters based on single-crystal Fe films is reported. The filters can be tuned over a broad frequency range with a relatively small magnetic field. Theoretical predictions based on a parallel-plate transmission line model agree qualitatively with the observations, but the measured attenuation per unit length is about 2.5 times smaller than predicted.<>
