Abstract

Nonuniform magnetization occurs in nonellipsoidal ferrite shapes such as rectangular slabs used in microwave phase shift and control components. A finite element magnetostatic solver is used here to develop modified slab shapes, which reduce high magnetic flux concentrations in the corner regions. Microwave finite element calculations show that similar phase shift performance is obtained in the standard and modified geometries. The proposed differential phase shifter cross sections should increase operating bandwidths and provide better stability in high-power devices.
