This work is a comprehensive theoretical study of a new class of structures – magnetoelectric gradient structures, which are a product of the integration of magnetoelectric mutliferroic layered structures and an artificial dielectric. In this paper, a mathematical model of the behaviour of a layered multiferroic structure in inhomogeneous electric and magnetic fields is built on the basis of solving Maxwell’s equations, taken in the magnetostatic approximation, and the equation of motion of the magnetization. Based on the constructed mathematical model, the influence on the spectrum of eigenwaves of stationary magnetic and electric fields, as well as the values of the dielectric constant of an artificial dielectric layer, are analysed. The results of the study confirm the possibility of designing a new class of electronically controlled microwave devices with a triple control mechanism: magnetic field – electric field – artificial distribution of dielectric constant.
