Abstract

Results of investigation concerning a new application of ferrofluids (magnetic fluids) in the doMayn of non-reciprocal X-band devices are shown. Values of ferrofluid slab position x₀, biasing field and ferrofluid saturation magnetization are determined for the optimum performance of an insulator. The advantages of using ferrofluids in non-reciprocal devices are also highlighted.
