| Research Abstract |
Three types of isolator operating in the vicinity of ferromagnetic resonance point : bottom mount type microstrip isolator, top mount type microstrip isolator and top mount type coplanar waveguide isolator, were developed. FEM electromagnetic simulation showed that the isolators are tunable in the frequency region from 450 MHz to 4. 6GHz, and excellent nonreciprocal transmission characteristics are obtainable. Nonreciprocal transmission characteristics of the isolator were actually confirmed using the isolator fabricated in trial. Design scheme of the isolator was also derived.
