Impedance permittivity permeability
WitrynaThis study investigates the impedance curve of magnetoelectric (ME) composites (i.e., Fe80Si9B11/Pb(Zr0.3Ti0.7)O3 laminate) and extracts the modified Butterworth–Van Dyke (MBVD) model’s parameters at various direct current (DC) bias magnetic fields Hdc. It is interesting to find that both the magnetoimpedance and MBVD model’s … WitrynaIf permittivity (er) is increases (1) lamda_g will be decreased, hence resonant frequency will reduce (2) maximum amount of E-fields will be confined in the dielectric media. Hence, less...
