Finite Element Modelling of Gyrotrpic Devives: Characterization and Analysis-Signal routing at Watts and KiloWatts is primarily handled by using waveguides or stripline structures containing magnetized ferrites. Over the last 50 years, many ferrite phase shift and control devices have been developed across the microwave spectrum for a wide range of power levels and now commercially available. However, many challenges remain to be addressed if this body of knowledge is to be extended to meet demands for miniaturization, broader relative bandwidths, and higher operating frequencies at reduced…mehr

Produktbeschreibung
Finite Element Modelling of Gyrotrpic Devives: Characterization and Analysis-Signal routing at Watts and KiloWatts is primarily handled by using waveguides or stripline structures containing magnetized ferrites. Over the last 50 years, many ferrite phase shift and control devices have been developed across the microwave spectrum for a wide range of power levels and now commercially available. However, many challenges remain to be addressed if this body of knowledge is to be extended to meet demands for miniaturization, broader relative bandwidths, and higher operating frequencies at reduced costs. Ferrite technology still remains to a great extent a black art because the design of ferrite phase shift and control devices is primarily based on the empirical approximations, circuit models and extensive experimentation. In this work a non-Hermitian gyrotropic finite element formulation is presented for the modelling of gyromagnetic structures.
