摘要: The aim of this work is to present a study microstrip directional couplers on magnetized ferrites. external dc magnetic field assumed be oriented in the y direction and its magnitude can varied, allowing control coupler properties. Hertz vector potentials, along ferrite magnetization direction, are used obtain dyadic Green's function an impedance matrix form. numerical solution based Galerkin's method applied Fourier transform domain. Results included as structural parameters biasing field.
