“…In nonreciprocal devices based on ferrite films of relatively modest thickness, the ohmic loss due to the finite conductivity of the metal layers of the device become a significant or even dominating part of the total loss. Neidert and Philips [120], and How et al [121]- [123] have described detailed analyses and supporting experimental data concerning this effect.…”

The development and current status of microwave ferrite technology is reviewed in this paper. An introduction to the physics and fundamentals of key ferrite devices is provided, followed by a historical account of the development of ferrimagnetic spinel and garnet (YIG) materials. Key ferrite components, i.e., circulators and isolators, phase shifters, tunable filters, and nonlinear devices are also discussed separately.

“…Any single energy functional must have its variation satisfy the governing quation (7) ( or (16)) valid for describing the time harmonic electromagnetic fields within the general medium, This goveming equation includes gyroelectric [7], gyromagnetic [8], chiral [9], gyroelectromagnetic [lo], gyroelectrochiral [ 101, gyromagnetochiral [9], and gyroelectromagnetochiral [lo] effects.…”

Although weighted residual techniques are extremely general and may be applied to both very arbitrary linear media of highly complex anisotropic character as well as nonlinear media, there are some places where one could cite the desire to maintain a variational approach. I t is for these cases that we here address the properties of the auxiliary method for treating differing degrees of anisotropy, including but not limited to g y r o e l e c t r i c , g y r o m a g n e t i c , , c h i r a l , g y r o e l e c t r o m a g n e t i c , g y r o e l e c t r o c h i r a l , gyromagnetochiral, and gyroelectromagnetochiral. What the adjoint method is capable of doing and its limitations will be discussed in view of the auxiliary method.

Advances in microwave monolithic integrated circuit (MMIC) technology have resulted in a dramatic reduction in the size and cost of active microwave circuits over the past several years. There have been several factors which have contributed to this success, some of the principal ones being more accurate device and circuit models, efficient user-friendly design tools, improved manufacturing processes, cost-effective packaging and high-volume testing enhancements. Efforts have been recently initiated to address many of these same factors to reduce the cost and size of MMIC-compatible circulators.
