Dispersion characteristics of magneto-inductive waves: comparison between theory and experiment

Thin-film magneto-inductive cables

“…The resonant element is a simple L-C circuit, which is magnetically coupled to its neighbours by a mutual inductance M as shown in configurations, in which M is positive and negative, respectively. MI waves have been studied extensively, in one-dimensional (1D) waveguides [12][13][14][15] and in 2D and 3D…”

Rotational resonance of magnetoinductive waves: Basic concept and application to nuclear magnetic resonance

“…18,19 They propagate along a set of magnetically coupled elements, which we shall take in the form of capacitively loaded metallic loops. In the simplest one-dimensional case, and in the approximation that only the nearest neighbor interactions are important, the relation between the currents in neighboring elements may be obtained by applying Kirchhoff's voltage law to the nth loop ͑see Fig.…”

“…17 A more detailed analysis of MI waves 18 was followed by experiments on capacitively loaded loops and Swiss rolls. 19,20 Applications of MI waves have been reported for delay lines, 21 phase shifters, 22 and microwave lenses. 23 An early application was for signal guidance in magnetic resonance imaging ͑MRI͒, to try and improve the signal to noise ratio.…”

A theory of metamaterials based on periodically loaded transmission lines: Interaction between magnetoinductive and electromagnetic waves

“…Apart from the main body of the experiments concentrating on the negative material parameter aspects of metamaterials, there is another set of experimental results available concerned with waves on an array of magnetically coupled resonant elements, namely, capacitively loaded loops, 15 'Swiss Rolls', 16 and SRRs. 17 It should be emphasized that these waves, known as magnetoinductive ͑MI͒ waves, are not simple analogs of longitudinal plasma waves.…”
