Abstract
We discuss magnetoelectric microwave devices. Combination of properties of ferrite and ferroelectric, and also the properties, induced by magnetoelectric (ME) interaction, find wide functional opportunities for creation of devices on the basis of ME materials. ME materials can be used for design of microwave phase shifters. Phase shifters will be most simply realised on effect of shift of a line of ferromagnetic resonance (FMR) under the action of a control electrical field. We shall consider an example of ME microwave through-passage microstrip phase shifter. As a working element a composite material, consisting of 95% from yttrium-iron garnet and of 5% from piezoceramics PZT is used. Phase shifters on ME materials have high performance, adaptability to manufacture, electromagnetic compatibility, radiating durability, thermostability, low power in control circuit.Keywords
