A W-band E-plane waveguide bandpass filter includes a rectangular waveguide configured to feed a W-band signal, and a dielectric substrate. The dielectric substrate is inserted into the center of the waveguide. The dielectric substrate is provided with a spoof surface plasmon polariton (SSPP) array configured to transmit a TM-mode surface wave to achieve the bandpass filtering response.

Illustrative embodiments of systems for characterizing resonance behavior of magnetostrictive resonators are disclosed. In one illustrative embodiment, an apparatus may comprise a first channel including one or more driving coils and one or more magnetostrictive resonators, the first channel having a first impedance; a second channel having a second impedance, the second impedance differing from the first impedance by an impedance attributable to the one or more magnetostrictive resonators; a signal source configured to apply an input signal to both the first and second channels; and a signal receiver configured to generate a combined output signal in response to output signals measured from both the first and second channels.
