    Ferromagnetic relaxation measurements in single-crystal yttrium-iron garnet (YIG) are given over the range of ° to °K. This is a report on the present status of YIG in which care has been taken to remove the extraneous rare-earth impurity ions and ferrous impurity ions. The measurements are reported in terms of the linewidth, ΔHk→0, of long-wavelength spin waves, which has been. DiTom Microwave Inc. N. Maroa Ave. Fresno, CA Tel: Fax: cally 3 and 4-port circulators have been produced. Tne 3-port or Y-junction circulator is the most common and is of major interest here. The possibility of such a device was proposed in (14). A scatter matrix analysis of a lossless reciprocal 3-port junction was made and it was shown that not all ports of the junction could be matched. MAFR MHz Single Junction Robust Lead Circulator. The MAFR is a single-junction circulator designed for wireless infrastructure applications. It operates over the frequency range of MHz to MHz.

A 4-port symmetrical coupling circuit met in the theory of YIG devices, such as nonreciprocal filters, limiters and circulators, is that of a junction of two orthogonal wires or other transmission lines. Although the scattering matrix description of this network has been analysed using Kirchhoff's laws, a more simple derivation may be obtained by the eigenvalue method.

YIG Resonators and Filters Hardcover $ Hardcover The stripline junction circulator is a unique three-port non-reciprocal microwave junction used to connect a single antenna to both a transmitter and a receiver.

Its operation relies on the interaction between an electron spin in a suitably magnetized insulator with an alternating radio. YIG film evaluation Narrow-linewidth epitaxial YIG films are necessary to achieve high-Q resonators and low-loss filters and a low power threshold in limiters. A non-destructive OH measurement technique has been developed in which the YIG film is placed close to a small hole in the narrow wall of a X-band waveguide, as shown in fig.

So, when the stripline circulator functions properly with the magnetic thin film, the effect of several parameters on the performance is evaluated using a numerical model.

After an optimized design is obtained, we transform the circulator under its coplanar version and finish the study.
