Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description2 The aim of the project is to determine the effect of geometrical parameters and magnetic field on the spectral and dispersion properties of an artificial topological insulator based on a two-dimensional two-periodical array of ferrite elements. For several topological insulator structures with a different rotation angle of ferrite ellipses in the unit cell, the possibility of varying the frequency of the stopband center by the external magnetic field is shown. It is numerically shown that with an increase in the intensity of the external magnetic field, the effect of modifying some modes of the topological insulator with a dipole structure on a quadrupole has occurs. The experimental research of the spectral properties of a combined artificial topological insulator based on a two-periodic array of elliptic ferrite elements is carried out. A qualitative agreement of experimental and theoretical results is obtained. Product Description popup.authors Ivzhenko Liubov I. Kalmykova Tatyana Vitalyevna Nakhimovych Marks I Odarenko Yevhen M.
