ABSTRACT:
A non-reciprocal latching phase-shifter uses a slab of a high-dielectric constant material embedded in ferrite to substantially concentrate the electromagnetic energy within the dielectric slab, thus eliminating the need for a conductive waveguide, and to provide for a small amount of energy leakage into the adjacent ferrite whose state of magnetization can be varied, thus providing for a variable phase-shift. In one embodiment, parallel high-K dielectric strips are sandwiched between grooved ferrite sheets to provide a low-cost phase-shifter array.
