A linked static/microwave "nite element solver for the analysis of ferrite-loaded waveguides with arbitrary geometry and magnetization is described. The magnetostatic solution of the DC bias circuit and ferrite magnetization curve are used to construct the tensor permeability for the microwave solve
A no¨el technique for the design of phase shifters is de¨eloped. The method makes use of the phase ¨ariation with frequency shown by frequency filters; this results in phase shifters that are small. These phase shifters pro¨ide near linear differential phase shift, and can be designed for both narro
## Abstract This article presents a Ku band 360Β° analogue phase shifter optimized with a genetic algorithm. Varactor diodes are used as the tuning elements. The device presents 360Β° phase shift on 11% bandwidth. At 12 GHz, the insertion loss is found to be β2.2 Β± 0.4 dB. Β© 2009 Wiley Periodicals, I
