A Model for the Magnetoimpedance Effect in Non-Symmetric Nanostructured Multilayered Films with Ferrogel Coverings

Magnetoimpedance (MI) biosensors for the detection of in-tissue incorporated magnetic nanoparticles are a subject special interest. The possibility ferrogel samples mimicking natural tissues with was proven previously symmetric MI thin-film multilayers. In this work, in order to describe effect non-symmetric multilayered elements covered by layer we propose an electromagnetic model based on solution 4Maxwell equations. approach is previous calculations distribution fields multilayers further developed case covering. role asymmetry film response multilayer–ferrogel structure analyzed details. field and frequency dependences, concentration dependences fixed frequencies dependence sensitivities obtained process both structures.
