Numerical Modeling of Patterned Magneto-dielectric Structures

Magneto-dielectric structures exhibit both electric and magnetic properties because they have relative permittivity and permeability values greater than one. Interest in magneto-dielectrics are growing due to their potential device applications, such as low profile antennas, magnetic read heads, non-volatile memories, etc [1]. We report the results of numerical modeling of the relative permittivity and permeability responses on magneto-dielectric structures with array patterns and we discuss the comparison of the results with modeling results obtained from the OOMMF software [2].
