A generation of microwave ferrite devices
Proceedings of the IEEE, 1988The development of microwave ferrite materials and devices over the last thirty years is traced. The status of materials, devices, and theoretical understanding prevalent in the mid-1950s is first reviewed. Developments in materials engineering of garnets and lithium ferrites in the 1960s and 1970s are described, along with the evolution of circulators

Multiferroic Based Microwave Devices
Advanced Materials Proceedings, 2016Recently, there has been significant interest on the fundamental science and technological applications of complex oxides and multiferroics. Low-power multiferroic have potential to fabricate and characterize frequency tunable, compatible with MMIC Technology, small light-weight for hand-held operation, cost-effective, high-frequency (>10GHz), devices ...

Microwave Magnetic Film Devices
2000Publisher Summary This chapter discusses the applications of magnetic films in microwave devices. Magnetic film microwave devices are based on a broad class of ferrimagnetic materials commonly referred to as “ferrites.” Both ferro- and ferrimagnetic materials exhibit the hysteresis effect, which is a nonlinear relationship between the applied ...

Journal of Physics E: Scientific Instruments, 1974
Avalanche diodes are finding an increasing number of applications as sources of microwave power in the frequency rane 1-100 GHz. There are two basic modes of operation; the IMPATT mode in which the diode behaves as a negative conductance in a resonant circuit, and the TRAPATT mode in which the diode acts as a fast switch which periodically discharges ...
